FORT PIERCE, Fla. (AP) — Authorities said a woman walking through security at the St. Lucie County Courthouse was found to have marijuana in her purse.

The sheriff's office reported a 21-year-old woman was entering the courthouse Tuesday morning when a private security officer ran her purse through a scanning device.

The scanner found a razor, a knife, scissors and padlock, which led to the officer to emptying out the purse. That's when he found a small bag of what appeared to by marijuana. A field test confirmed it.

The woman was arrested by deputies at the courthouse and charged with possession of less than 20 grams of marijuana. She was later released on $500 bail.
