"I urge all volunteers not to raise their hand n to stay calm n non-violent. U shud be prepared to lay down ur life but never raise hand," Kejriwal tweeted after violent clashes were reported between BJP and AAP workers in Lucknow and Delhi. 

As he embarked on his four-day tour to verify Modi's claims of providing water, power, education and healthcare to people of Gujarat, Kejriwal was taken to Radhanpur police station in north Gujarat and allowed to go after half an hour.
