The accused identified as 35-year-old Mahaveer, a resident of Dichaon Village in Baba Haridas Nagar, killed his daughter last night and surrendered to police this morning.
"Mahaveer strangulated his daughter to marry his lover as she was aware about her father's illicit relationship and she was not ready to accept the other woman as her step-mother," said a police official said.
Mahaveer's wife had on April 23 committed suicide by jumping before a train after she came to know that Mahaveer was having illicit relationship with their neighbour.
A police team reached the spot and nabbed him.
A case of murder has been registered and further investigation was underway, police said.
