According to the official, Ramkumar, an unemployed engineering graduate, has two sisters. His father works in BSNL and mother is a housewife. "It seems the family is unaware of his alleged deed," the official told IANS. He said Rajkumar's neighbours were reluctant to speak about the youth after coming to know the reason behind the police action. "We have to check with the college authorities and others to know about him," the police said. Speaking to a television channel a neighbour said Ramkumar is a silent person.
