WATERBURY (AP) - The Vermont State Police have renewed their agreement with the state Department of Corrections to help fight drug smuggling at prisons with the use of police dogs.

The police are providing dog teams on a pre-planned and on-call basis to search correctional facilities, including during visitation hours.

State police, in cooperation with the Department of Corrections, have investigated several attempted smuggling and contraband cases in the last few months.

Since the start of 2012, the VSP have investigated about 35 reported incidents of transportation of alcohol, tobacco, or regulated drugs into places of detention.
