Mumbai: Arvind Kejriwal should have checked the antecedents of his Principal Secretary Rajender Kumar, whose office was yesterday raided by CBI over alleged graft, social activist Anna Hazare said today amid the face-off between the Centre and Delhi Chief Minister on the issue.

"Instead of fending off allegations now, Kejriwal should have checked his background earlier. Arvind has always been fighting against corruption and I have always told him to have people of good character around him," Hazare, once a mentor to the Delhi CM, told reporters at his native place Ralegan Siddhi.
