LUCKNOW, Aug. 4 -- A first information report (FIR) was registered against three unidentified people after a group of men, said to be part of the Kanwar Yatra, allegedly ransacked and pelted a private school van, carrying about seven children, with stones in Lucknow's Chowk area on Monday morning.

Eyewitnesses alleged that the men allegedly smashed the van's windows in front of policemen.

Police, however, did not officially mention if the men on the bike were Kanwariyas despite eyewitnesses' claims.

Police, which initially claimed it was a "small matter", later registered the FIR...
