Lakhvinder Cheema and Gurjeet Chohan Allegedly Murdered by Lakhvir Singh, West London, London, England
This source-based behavioral analysis does not establish a clinical diagnosis, motive, or legal finding.
The source presents a relationship-centered escalation involving a long-term concealed affair, a threatened breakup, jealousy, reported threats, and alleged repeated poisoning. These observations describe reported behavior and narrative-supported relationship dynamics, not a clinical diagnosis. The conviction is a legal outcome, while the psychological pathway remains limited to the source's account.
Singh reportedly maintained a double life involving marriage and a long-term affair with Cheema. When Cheema became engaged to Gurjeet through family arrangements, Singh reportedly rejected the end of the affair, monitored the couple, threatened Cheema's home, and allegedly escalated to poisoning. Gurjeet was described as a recently arrived young fiancée with limited local support who became an additional target in the reported conflict.
The reported pathway moved from concealed attachment and emotional dependence to relationship loss, jealousy, surveillance, threats, alleged poison acquisition, an earlier poisoning attempt, and a later fatal attack. Post-incident, the source describes limited emotional expression by Singh in court, but does not provide sufficient evidence to interpret that behavior clinically.
Each entry separates the reported behavior or state from the analytical strength of the available narration.
| Behavior / construct | Person / subject | Detailed case context | Evidence |
|---|---|---|---|
| Infidelity or competing attachment Relationship stressor | Lakhvir Singh SuspectLover of victim |
The reported affair lasted approximately 15 years and continued across separate households. Singh reportedly became pregnant by Cheema twice and terminated both pregnancies at his request, which the source presents as evidence of the intensity and personal cost of the attachment. This relationship structure created a persistent conflict between her marriage and her bond with Cheema. Context or trigger: Singh was married while maintaining a long-term affair with Cheema. Reported expression: The source reports that Singh lived a double life, caring for her husband in Southall while traveling to visit Cheema in Feltham. The competing attachment remained central to her identity and later conflict. |
Explicitly reported Confidence: High |
| Separation or abandonment threat Loss or threat | Lakhvir Singh SuspectLover of victim |
Cheema's engagement represented the loss of Singh's long-standing romantic relationship while her marriage was already described as loveless. The source says Singh saw her life unravel and viewed the relationship as ending. This perceived abandonment preceded threats, surveillance, and alleged violence. Context or trigger: Cheema announced that he would marry Gurjeet and end the affair. Reported expression: The source describes Singh as distressed when Cheema ended the relationship and reports that she tried to persuade him to continue the affair. |
Narrative-supported psychological state Confidence: High |
| Jealousy Emotional state | Lakhvir Singh SuspectLover of victim |
The source explicitly characterizes Singh as jealous, angry, and upset after Cheema's new engagement. Her reported monitoring of the couple focused on whether the new relationship was becoming physically intimate. The jealousy construct is supported by the reported rival-focused behavior, although it does not independently establish causation. Context or trigger: Cheema's engagement to Gurjeet and Singh's observation of the couple together. Reported expression: Singh reportedly spied on Cheema and Gurjeet and threatened to burn his house if he slept with Gurjeet. |
Explicitly reported Confidence: High |
| Chronic interpersonal conflict Relationship stressor | Lakhvir Singh and Lakhvinder Cheema |
The relationship reportedly shifted from a long period of intimacy to an unresolved breakup. Singh allegedly sought continuation of the affair, while Cheema reportedly refused to remain involved in the emerging triangle. This prolonged dispute formed the immediate relational background to the reported attacks. Context or trigger: Cheema's decision to end the affair and marry Gurjeet. Reported expression: The source reports pleading, cajoling, threats, and conflict over whether the affair could continue. |
Narrative-supported psychological state Confidence: High |
| Rumination or fixation Cognitive pattern | Lakhvir Singh SuspectLover of victim |
The reported conduct indicates persistent focus on Cheema's relationship decision and Gurjeet's role in it. Rather than ending contact after the breakup, Singh allegedly continued surveillance and used her access to the home. The repeated attention to the same grievance is consistent with a source-supported fixation pattern, though no clinical inference is made. Context or trigger: The threatened loss of her relationship with Cheema. Reported expression: Singh reportedly continued pursuing the relationship, monitored the couple, retained access to Cheema's home, and allegedly returned to the conflict through two poisoning attempts. |
Analytical inference Confidence: Moderate |
| Premeditation and planning Planning or impulsivity | Lakhvir Singh SuspectLover of victim |
The reported sequence contains several preparation indicators: travel and poison acquisition, possession of the plant material, a first attempt, and later use of a known meal in a home to which Singh had access. These details support deliberate preparation as described by the source. They do not independently establish every element of legal intent beyond the reported conviction. Context or trigger: The reported decision to obtain and use a toxic plant after the relationship breakdown. Reported expression: The source reports travel to India, acquisition of aconite, an earlier poisoning attempt, and a later alleged attack using access to the victims' food. |
Narrative-supported psychological state Confidence: High |
| Emotional escalation Escalation | Lakhvir Singh SuspectLover of victim |
The reported emotional language intensifies across the chronology, from distress over the engagement to anger and jealousy after observing the couple. Threats against the house preceded the reported acquisition and use of poison. This escalation is a relationship pathway description rather than a clinical assessment of Singh's emotional regulation. Context or trigger: The ending of the affair and Cheema's impending marriage. Reported expression: The source describes a progression from distress and pleading to anger, jealousy, threats, and alleged poisoning. |
Narrative-supported psychological state Confidence: High |
| Situational vulnerability Victim vulnerability | Gurjeet Chohan Victim |
Gurjeet was described as newly arrived, socially isolated, and expecting to marry Cheema. Those circumstances may have reduced her immediate access to local support during the alleged attack. The source presents her as an unintended or rival target who survived but sustained reported life-changing internal injuries. Context or trigger: Gurjeet's recent arrival in England for an arranged engagement. Reported expression: The source reports that Gurjeet spoke no English, knew scarcely anyone in England, and required intensive medical treatment after the poisoning. |
Explicitly reported Confidence: High |
| Instrumental aggression Offender behavior | Lakhvir Singh SuspectLover of victim |
The alleged method was indirect and directed at a specific relationship configuration. The source describes the poisoning as serving a revenge objective after the breakup and as targeting both the former lover and the new fiancée. This interpretation is source-grounded but remains bounded by the documentary account and legal outcome. Context or trigger: The reported objective of ending Cheema's new relationship and seeking revenge. Reported expression: The source reports alleged use of poison against both Cheema and Gurjeet through food, with Cheema dying and Gurjeet surviving. |
Narrative-supported psychological state Confidence: High |
