Lucknow: The prime accused in the murder of Chandan Gupta in Kasganj was arrested today as the strife-torn western Uttar Pradesh town, which saw communal clashes last week, moved towards normalcy despite tension in some pockets, officials said.

The Uttar Pradesh government submitted a report on the incidents in Kasganj to the Union Home ministry conveying that the police were probing the violence and also whether it was pre-planned, an official said.

"Saleem, the main accused, has been nabbed," IG, Aligarh range, Sanjeev Gupta said.

Aged below 30, Saleem, and his two brothers, Naseem and Waseem, were accused of killing 22-year-old college student Chandan Gupta, police officials said.

The killing had led to further violence last week.

At least three shops, two buses and a car were torched after Gupta died of gunshot wounds. Communal clashes occurred in the town last week following stone-pelting by a mob on a motorcycle rally taken out to celebrate Republic Day.

Over 150 arrests have been made in connection with the Kasganj violence, the officials said.

"Saleem has admitted that he had opened fire at Chandan," IG Sanjeev Gupta claimed.

While Saleem was hiding in Kasganj, his two accused brothers were yet to be traced, police officials said.

Kasganj SP Piyush Srivastava said notices pertaining to attachment of properties of the accused were pasted outside their houses.

District authorities, meanwhile, stopped a Congress delegation in Mirhachi area of Etah, close to Kasganj border.

The delegation was denied permission due to law and order issues, officials said.

District Magistrate, Kasganj, R P Singh refused permission to the Congress delegation apprehending that their visit to the troubled areas might create more problems.

Tension still prevailed in a few pockets of the town.

Police said normalcy was slowly returning while the security personnel had intensified patrolling in sensitive areas.

Stray incidents of violence were reported from Kasganj yesterday but the situation was by and large peaceful today, they said.

The UP government, meanwhile, sent a report to the Union Home ministry on the violence and steps taken to control it.
