Protestors set a railway station on fire at Sanganer in Jaipur as unrest continued in Rajasthan for the fifth day on Saturday over the Gujjars' agitation for Scheduled Tribe status, an official said.

The communication system and official documents were gutted in the fire late Friday night as the Railway Protection Force personnel were allegedly absent from duty.

The protestors sprayed petrol after pushing out a sole employee there and lit the fire, he said. Two motorcycles parked outside the station were also torched.

Jaipur SP (East) V K Singh said additional force was deployed at all stations on Jaipur's Gandhinagar, Durgapura, Jagatpura and other railway stations as a precautionary measure, he said. A case has been registered and efforts were on to nab the accused.

As a precautionary measure, the state government has sealed the Haryana and Uttar Pradesh borders, a home department official said, adding that only valid passengers will be allowed to enter after thorough checks.     

The police foiled attempts of rioters to create trouble in the state capital and arrested five of them in the wee hours, he said.

Meanwhile, the Rajasthan State Road Transport Corporation has begun bus services on the Jaipur-Delhi route from both sides and paramilitary forces will provide security, an official spokesman said.
