Security has been tightened in the city and its adjoining areas after angry members of a community, protesting 'tardy probe' into the death of girl and rape of another of their community, set afire three state buses near Rajkot on Tuesday.
Two buses of the State Transport Corporation were burnt near Tramba town on city's outskirts while one was torched on Rajkot-Ahmedabad national high way number eight near Kuvadava town.
The driver of one of the buses burnt at Tramba sustained burn injuries and was rushed to the civil hospital in Rajkot, fire brigade sources.
Following the incident, the transport corporation has diverted or cancelled buses through "sensitive routes", official sources said.
Police have also increased its patrolling on highways to check any untowards incident, they said.
The Koli community members were protesting police's "failure" to nab the two suspects in the the death of one and sexual assault on another girl of their community.
Two girls belonging to the community had gone to Datar shrine in Junagadh on May 13 with their families, when they were abducted by two men identified as Mohan Hamir and Ramesh Bhadu, who raped a girl and murdered another when she challanged them.
The community members, demanding speedy probe, have also started an indefinite fast in front of the collectorate in Rajkot, that has entered the fourth day on Tuesday.
