A Treasure Coast man has been arrested after authorities say he caused the evacuation of a courthouse by leaving a doll outside.

Fort Pierce police say 22-year-old Tyler Long was charged with disorderly conduct Thursday.

A man was caught on video Jan. 6 climbing the platform of a flagpole at the federal courthouse in Fort Pierce and leaving an object before running off.

Though authorities quickly identified the object as a baby doll, the courthouse was closed and a police bomb unit called in. It did not contain any explosives.

Police say Long thought the doll was "creepy" and thought it would be fun to scare someone with it.

He was being held on $20,000 bail. Jail records didn't list an attorney.
