Bhuj (Gujarat): AAP leader Arvind Kejriwal today apologised for his party workers' behaviour in Delhi and Lucknow while protesting his "detention" and urged them to stick to non-violence.

"It was going to happen...some of them retaliated after they were attacked...I apologise for their behaviour and I once again urge them to remain non-violent," he told reporters here in response to a query on the arrest of over a dozen AAP workers in Delhi. AAP workers had yesterday clashed with BJP activists outside the saffron party headquarters in Delhi and Lucknow after Kejriwal's car was damaged in Gujarat in retaliation to protests against his brief "detention" in the state.
