Agitating lawyers today clashed with police and went on a rampage torching a vehicle and vandalising a check post to protest against yesterday's police action against them during a march to the Rajasthan Assembly.

DCP Mahendra Singh was injured as the protesters pelted stones and fought pitched battles with the police, which used batons and tear gas shells to disperse them.

"The lawyers pelted stones at police from sessions court building and collectorate building around noon. They burnt a police van and vandalise a police chowky in the collectorate building," Additional Commissioner of police Biju George Joseph told PTI.

"In the heavy stone pelting, DCP, North, Mahendra Singh received head injury," he said, adding "police had to resort to lathicharge and tear gas shells were lobbed to control the tense situation".

The lawyers are on an indefinite strike from today against yesterday's police action which left 30 advocates injured when the protesters were marching near the state legislative building to press their demands including a monthly stipend for new practising lawyer for a period of five years and housing scheme.

Security personnel were deployed in strength in the area to control the situation even as lawyers claimed that a large number of their colleague were "hiding" in the session court building and the nearby collectorate building to escape police action.

Even as violence erupted outside for the second day, the issue was raised in the Assembly with the opposition demanding suspension of police officials and lodging of FIR against them for the crackdown on lawyers but the Rajasthan government justified the police action.

The BJP also demanded a judicial probe into yesterday's incident.

Following fresh clashes today, Kataria and other MLAs demanded a statement from the government in the Assembly. They trooped into the well and created uproar demanding clarification from the government after which Beniwal said that lawyers pelted stones at police which prompted them to take action.

Beniwal informed the House that one DCP, one head constable and one constable were injured in the stone pelting and a few lawyers were also injured.

He assured the house that action would be taken against policemen if they were found guilty in the matter.

As the vociferous protest by the opposition continued, deputy speaker adjourned the House for the day.

About a dozens private vehicles parked near the collectorate were also damaged during the violence with lawyers and policemen blaming each other for it.

Advocates alleged that rubber bullets were fired though the police did not confirm it.

High Court judge RS Chauhan went to the spot and collected details in order to brief Chief Justice Amitava Roy about the incident.

Addl Commissioner of Police Joseph said in the evening that the situation was under control.
