"In Lucknow, Delhi and Gujarat violence by BJP shows the restlessness of Modi over his greed of becoming prime minister. People of India will show them the way.
"Modi has a violent past and he knows no other way to win election. Feared of getting exposed on his bubble of growth he can go to any extent," party leader and former law minister Somnath Bharti tweeted after the incident.
"Police has badly beaten up AAP volunteer Pawan Pande in parliament street lock up. Police is taking orders from Modi?" he tweeted.
As Arvind Kejriwal 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.
AAP's state convener Sukhdev Patel claimed that Kejriwal was detained but police denied it saying they had only "briefed" Kejriwal on the Model Code of Conduct which came into force today with the declaration of poll schedule.
