Charleston County sheriff’s deputies on Thursday arrested a Johns Island man accused of sexual assault.

Dwayne A. Thompson, 44 of Bohicket Road, is charged with committing a lewd act on a child under the age of 14 and simple possession of marijuana, jail records show.

Thompson was named in connection with an incident that happened between January and June of 2008.

A teenage girl who is in the custody of the Department of Juvenile Justice told a social worker that she and another girl would lie in bed with Thompson and watch horror movies, an incident report states.

Thompson fondled the girls while they were on the bed, the report said.

Two adults may have known about the assault, but the incident went unreported at the time, deputies said.
