London, Nov. 14: A jealous Brit Sikh mistress stabbed a pregnant Muslim teenager to death in her own bedroom, a court here has been told.

Dentistry student Harmohinder Kaur Sanghera knifed the wife of Sair Ali out of jealousy and desperation, the Daily Mail reported.

Sana Ali, 17, of Bury, Greater Manchester, received 42 separate wounds to her body, including one that penetrated deep into her abdomen. She was 11 weeks pregnant at the time of her death.

Peter Wright, the prosecutor in the case told the Manchester Crown Court that Sanghera, 23, had been having an affair with Sair since July 2005.

The relationship continued despite the Alis' arranged marriage in December last year, although Ali hid the fact from Sanghera for most of the time.

Wright said whoever murdered Mrs Ali at her home in Throstle Grove had deliberately lifted her top while she lay on the bedroom floor and stabbed her in her abdomen.

"The deeply personal element points unhappily, and unequivocally, to the identity of the killer being the defendant, " he said.

"You may conclude from the evidence that the defendant not only resented Sana Ali but resented that she was expecting the child of her husband. "

He said the relationship between Ali and Sanghera ended when she killed her rival for his affections in May this year.

Mrs Ali lived in a large four-bedroom detached home on the outskirts of Bury with her husband and his parents following the arranged marriage.

Sanghera denies that she murdered Mrs. Ali. The trial has been adjourned till Thursday. (ANI)
