The Delhi police on Tuesday gave a clean chit to the government in the telephone tapping allegations made by Samajwadi Party General Secretary Amar Singh and said it was a case of forgery and cheating.

Delhi Police Commissioner K K Paul, in a report submitted to Home Secretary V K Duggal, ruled out the involvement of the government in the matter as alleged by Singh.

"The report clearly rules out the role of the government in the matter. It is a case of forgery and cheating," Duggal said.

The report, apprising the progress in the investigation into the charges, also talked about the arrests made so far.

Three people, including two owners of private detective agencies, have been arrested in the tapping case so far.

Police believe that one of the two detectives had forged letters seeking permission to intercept the telephone of Amar Singh.
