Selangor police have detained 137 individuals since the launch of Ops Khas Cantas 2 on Aug 6, said state deputy police chief, Deputy Comm Datuk Mohd Fuad Abdul Latiff.

Of the amount, 76 would be charged in court with having links to the underworld.

He said the 76 suspects, aged between 20 and 50, were identified based on their tattoos.

They were suspected members of Gang Satu Hati, Gang 04, Gang 36 and other groups which have since been declared illegal.

"Their tattoos showed their gang affiliations," Mohd Fuad told reporters at the Ara Damansara police station today.

He had earlier witnessed the disposal of 3,659 units of computers and gambling machines.

Mohd Fuad said in Selangor alone, police have raided 447 illegal gambling dens and detained 400 workers.

He said they have also seized 7,260 units of computers worth RM5.8 million and RM 40,043 in cash.
