The wall was constructed in police lines to stop commutation of public for security reasons. The issue has been a bone of contention between police and public, according to whom the structure was a problem as they had to take a longer path to commute.
Yesterday, SP MLA Radheyshyam Jaiswal along with his supporters demolished the wall, police said.
A case has been registered under various sections of the IPC for destruction of public property, they said.
Meanwhile, the MLA denied his involvement in the activity.
