After a government website published online that twenty students will be issued caste certificates, police raided the Tehsildar's office which issues the certificates.

Police said the arrested touts had revealed during interrogation that these twenty students had approached the Tehsil's office through them.

The cops said there is a nexus involving touts, DU officials and government employees who run the fake certificates business.

A senior police official said they have not seized anything from the office. He added that some officials at the Tehsildar's office have been questioned.

The Crime Branch of Delhi Police has also raided the hideout of Satish, an aide of Himanshu Gupta who was held last Saturday. However, Satish managed to give the cops a slip.

The official said legal action will be taken against students who got admission in any university using fake caste certificates.
