He stabbed her repeatedly, slashed her neck, and even tried to behead her before running away.
A 60-year-old man stabbed his wife to death in broad daylight in India's capital New Delhi on Wednesday.
The police said the couple, who were travelling in a car, were seen arguing by witnesses around 11.30 am. The accused, Mukesh Monga, then allegedly took out a knife and stabbed his 58-year-old wife, Manju, to death, news agency PTI reported.
The fight allegedly erupted over a phone call that Mrs Monga received.
Mr Monga has reportedly told the police that he was upset with his wife for being friendly with another man and speaking to him on the phone in his presence. The couple had been married for 30 years.
"The family is in a state of shock and we haven't been able to question them in detail. The accused, however, claimed that he was angered by his wife's reply when he asked her who was on the phone," a police officer told PTI.
The police are investigating whether the murder was planned or happened in a fit of rage. That he had a knife in the car raises suspicion that he had planned it, a police officer told PTI.
Mr Monga allegedly had a history of physically assaulting his wife, the police said.
The accused slashed his wife's neck and even tried to behead her before running away. Horrified witnesses chased Mr Monga, catching him near a school, where a security guard called the police.
Mrs Monga died near the boutique in the capital's upscale Anand Niketan area where she worked. Mr Monga had not been home for a day and suddenly arrived on Wednesday morning to drop his wife off at her boutique.
The couple stayed in Hari Nagar in west Delhi with their daughter, 30, and son, 29.
The family's neighbours have alleged that Mr Monga was a heavy drinker and that the couple fought constantly. He worked at his sister's music school as a guitar instructor. Their children have reportedly told the police that the household ran on Mrs Monga's income.
