The head of Charleston County's detectives has been arrested after neighbors told police he was on a roof, staring into the bedroom window of an adjoining home, authorities said.

Sheriff's Capt. Jesse Gene Hammet, 43, was placed on administrative leave after North Charleston police arrested him Friday on two counts of violating the state's Peeping Tom law, Charleston County sheriff's spokesman Capt. John Clark said.

A neighbor called police Thursday and said she saw Hammet get on the roof of his townhouse, scamper across to an adjoining townhouse and peer inside the bedroom window of a 24-year-old woman for about five minutes, according to an arrest warrant.

The investigation continued Monday, with a fire department ladder truck helping North Charleston police examine the roof for fingerprints and other clues.

Hammet has worked for the sheriff's office since 1990. He has done several jobs from courtroom security to narcotics investigations and took over as the head of detectives about a year ago, Clark said.
