A 25-year-old man in Delhi was arrested for allegedly killing his girlfriend's father in Delhi for rejecting his request to marry her, the police said on Monday.
The accused, Suraj Kumar, a resident of Sonia Vihar, worked as a housekeeper at Palam Metro Station, they said.
He was arrested when he was about to escape from near a local auditorium.
On Saturday, the body of 50-year-old Bijender Singh was found with multiple injuries to his head at his home in the same neighbourhood, Sonia Vihar, a senior police officer said.
It was also found that there was no forced entry into the house, he said.
Deputy Commissioner of Police (Northeast) Ved Prakash Surya said investigations revealed that the young woman was the adopted daughter of the victim, who was strongly against her relationship with Suraj.
When the woman, 24, remained adamant on continuing the relationship, her foster parents left the her with her biological parents in Uttar Pradesh's Moradabad district.
Suraj's parents reportedly approached the woman's parents in Moradabad with a marriage proposal but Bijender Singh urged them not to accept it, which allegedly infuriated Suraj.
"During interrogation, Suraj disclosed that after Singh rejected him for his daughter, he got angry and made a plan to kill him. He started following Singh and his wife from November 28," he said.
On the day of the incident, the accused took a knife from the couple's kitchen and allegedly stabbed him on the head and later took a pressure cooker from the kitchen and hit him on his head several times till he became unconscious, the police officer said.
