Police on Friday beefed up the security outside the house of Chandan Gupta after his family alleged they were being threatened after the death of their son in Kasganj communal violence on the Republic Day, an officer said.
Chandan Gupta's father Sushil Gupta sought police protection after he was allegedly threatened on Thursday night outside his house in Kasganj.
Sushil Gupta said he was sitting outside the house when some youth from the neighbourhood came and threatened him that they won't spare him.
Gupta said he was so scared that he had decided to apply for a gun license and sought protection from the Yogi Adityanath government.
The prime accused in the killing of Chandan Gupta, Salim, has been arrested and is in jail though his two brothers, also accused, Naseem and Waseem are still at large.
The Guptas said they were worried about the fact that men accused of killing Chandan Gupta could harm them.
Chandan Gupta was shot dead during a procession by the Bharatiya Janata Party's student wing Akhil Bharatiya Vidyarthi Parishad (ABVP) at Bilram Gate on January 26.
The killing triggered communal riots and the district was singed with arson and vandalism, leaving some persons injured and property gutted.
More than 150 persons have since been arrested.
