Assistant superintendent of Prohibition and Excise M. Ravindra Prasad, head constable Verma and a constable, were suspended on Thursday.
All the three were posted at Gajuwaka and were allegedly helping smugglers in ganja smuggling activity.
Based on a statement given by a smuggler who was arrested sometime ago by Devarapalli police, Superintendent of Police Rahul Dev Sharma had submitted a report to the Excise Department.
The suspension was based on the report and an inquiry, said Assistant Commissioner of Excise (enforcement) SVVN Babji Rao.
