Train and buses services resumed normal services as leaders of the hard-line Shiv Sena party called for restraint after mobs took to the streets on Sunday to protest the smearing of mud on a statue of party founder Bal Thackeray’s late wife Meenatai.

“We have told workers to stay calm. But we want the government to arrest those responsible and we want the arrests to be made quickly,” said Uddhav Thackeray, the party’s chief and Bal Thackeray’s son.

The violence Sunday spread to towns and cities across the western state of Maharashtra. Bombay, where the statue is located, is the state’s capital.

Police fired tear gas to disperse rioters, who in many places hurled stones at shops that refused to shut down. Sena workers also held demonstrations that stopped buses and trains. No injuries were reported.

Bombay’s top police officer made a televised appeal late Sunday urging Sena supporters to refrain from violence.

“Strict action will be taken against anyone who takes law into their own hands,” he said. “We are investigating the incident and will take action against those responsible.”
