A lawyer suffered gunshot injuries during a clash between agitating advocates and Uttar Pradesh State Road Transport Corporation employees near the high court building in Lucknow on Saturday.
The lawyers, demonstrating against Friday's police cane-charge on them, had an altercation with the employees at a nearby roadways depot, the police said.
Some shots were fired in the air. A lawyer who received bullet injuries was admitted to a hospital. The lawyers alleged the roadways employees fired the shots, but the latter denied it.
Senior Superintendent of Police Kamal Saxena said the police were verifying what happened.
Work at the courts was paralysed for the second day as lawyers abstained from judicial work, protesting against the cane-charge.
Lawyers boycotted work at Mainpuri, Jaunpur, Azamgarh, Basti, Unnao and other places to express solidarity with their colleagues against the police action.
Thirty-six persons, mostly lawyers, were injured in a clash between advocates and the police on Friday after an argument over the checking of vehicles.
In Kanpur, agitating lawyers assembled at the bar association office and condemned the police action on the Lucknow lawyers. They demanded compensation to the injured advocates.
The district administration had made tight security arrangements in and around the court premises.
