A case under sections 302 (murder) and 307 (attempt to murder) was registered against the MP and others in the Phoolpur police station, police said.

Over a dozen people were injured in the clash. A huge battery of police personnel have been deployed in the city to prevent any untoward incident.

The Azamgarh-based Uttar Pradesh Ulema Council, the most vocal of half a dozen Muslim political parties, emerged about six months ago after two Muslim youth of the district were shot dead by the Delhi Police in a gun battle Sep 18, 2008, in the Batla House locality of the national capital.

Over a dozen other youth were picked up subsequently by the police, and charged with being involved in anti-national activities. The council had accused the police of indiscriminately rounding up people from Azamgarh.
