Denying reports that Maharashtra government had ordered a review of Anna Hazare's security after attacks on Team Anna members Prashant Bhushan and Arvind Kejriwal,the state Home Department today said cover provided to the anti-graft activist was "more than adequate". "We have already provided 'Z' category security to Hazare. There have been no orders for reviewing the security," a senior official said. "Such reports (that Hazare's security is being reviewed) are a figment of someone's fertile imagination," he said,following the reports from a section of media that Maharashtra DGP ordered a review of Hazare's security after IB alerts. Hazare is currently on 'maun vrat' (vow of silence) and is not undertaking any kind of travel. Team Anna member Bhushan,a prominent lawyer,was recently assaulted in his chamber over his controversial remarks on Kashmir,while Kejriwal was attacked with a sandal yesterday while going to address a rally in Lucknow.
