Visitors to St. Clair County's courthouse are being put on notice that bringing drugs into the building isn't a bright idea.

Three people have been arrested at the Belleville courthouse in less than a week after they allegedly were found to be carrying drugs at a security checkpoint.

Sheriff's officials say bailiff Josh Pea arrested a man Monday who was carrying marijuana in one of his pockets. The man was charged with misdemeanor marijuana possession.

Last Wednesday, Pea nabbed a man who swallowed a bag of suspected cocaine he refused to turn over the bailiff. That man was charged with obstructing a peace officer.

The next day, Pea arrested another man at the checkpoint who was also carrying marijuana.
