A resident of Barauli, Shayam Manohar (55), who works as a carpenter, yesterday had a fight with his 30-year-old mentally challenged son Dipu.
After the fight, Dipu left the house. Manohar then went to look for his son, who was sitting on a tree. He asked Dipu to come down repeatedly, who refused to do so. Later in a fit of anger, Dipu hit his father with a brick several times, they said, adding the victim died on the spot and the accused fled from the spot.
The body has been sent for post mortem and a search is on to nab the accused.
