A 22-year-old man surrendered before the police here after allegedly killing his parents and niece with a brick and hammer, officials said on Tuesday. Accused Saurab surrendered at the Gandhi Park police station late on Monday, saying he killed his father Omprakash (62), mother Somvati (60) and niece Shiva (4).

Omprakash, a retired government employee, had funded his elder son`s gymnasium but refused to financially help or give a share of the property to Saurab, who was unemployed, to set up his business. This infuriated him, the officials said.
