AAP supporters Wednesday staged a protest outside the Tihar Jail here, after party leader Arvind Kejriwal was taken inside the jail premises following a court's order sending him to judicial custody, police said.Aam Aadmi Party leaders Manish Sisodia, Yogendra Yadav and Sanjay Singh sat on a protest around 7 p.m.The protestors raised slogans against Bharatiya Janata Party leader Nitin Gadkari."We are here in solidarity with our colleague. It is ironical that those who are fighting against corruption are behind bars while the corrupt are outside," said Yogendra Yadav.A Delhi court Wednesday sent Kejriwal to two-day judicial custody after he refused to furnish a personal bail bond in a defamation case filed by Gadkari.
