Delhi Chief Minister Arvind Kejriwal on Thursday urged Prime Minister Narendra Modi to release those arrested for pasting posters criticising him on walls in Delhi. Mr Kejriwal made the call at the Aam Aadmi Party's (AAP) 'Jansabha' at Delhi's Jantar Mantar, timed with the martyrdom day of Shaheed-e-Azam Bhagat Singh, Rajguru and Sukhdev. "They filed 138 FIRs for putting posters in Delhi within 24 hours. They arrested six people. A printer and six innocent poor people were putting up posters on the walls. What is going on? Is the Prime Minister's health fine?" Mr Kejriwal said. He said leaders are invited to join the BJP with the promise that they could be "openly corrupt". (Video credit: PTI)
