Arshad Ali allegedly stabbed to death Sabina (25) in her Sangam Vihar house on April 29 night and fled from the spot.
Ali was apprehended from Hauz Rani yesterday on a tip-off, DCP (South) Chhaya Sharma said.
"He told us that he had infatuation on his daughter- in-law and wanted to have physical relations with her. He was staying with his son Sabir. At that time, he teased his daughter-in-law but the matter was sorted out with the intervention of family members.
"No complaint was lodged with the police then. On the fateful day, he went to Sabina's room and found her with her daughter. He tried to convince her for having a relationship with him but she refused and slapped him," Sharma said.
Enraged at this, Ali stabbed Sabina repeatedly and fled from the spot. He threw the blood stained knife and shirt in the hilly area in M Block of Sangam Vihar.
The suspicion had fell on Ali after their landlord had found the accused climbing down the stairs in blood-soaked clothes and with a knife.
