A notorious rowdy sheeter of the city who was under judicial custody has been detained under the Goonda Act, police said.

Shaikh Mohamad Asgar alias Maheem, 48, has been involved in 17 criminal cases including murder (2), attempt to murder (1), rioting (3) and kidnap (4) cases, City Police Commissioner Shankar Bidari said in a statement today.

"Any amount of action under law in existence has so far failed to deter him from indulging in serious bodily crimes against an innocent public", the statement said.
