MAU (UP): Tension continued to prevail in this town on Sunday as unidentified persons allegedly tried to set ablaze a mosque, officials said.

The incident occurred in Muhammadpura area but timely intervention by police foiled the bid to set the mosque ablaze.

An FIR has been registered in this connection, they said.

Meanwhile, some office-bearers of the city bar association, who had threatened to immolate themselves on Monday if the killers were not arrested, continued to stick to their stand despite requests by the administration.

Security personnel maintained tight vigil in the city where violence had flared up after the killing of a student Ankit Kumar Soni on August 2.

Police had registered an FIR against two unidentified persons in connection with the killing but no arrests had been made.

Twenty people were killed and scores injured in riots in the town last year during the Dussehra festival.
