The FBI is investigating whether a Texas courthouse break-in by five foreign nationals was a prank or possible act of terror.
The crime at the Bexar County Courthouse triggered a scare, sending FBI agents and bomb-sniffing dogs to the scene.
Some of the men, all in their 20s, were found inside the building. Others were found in a nearby RV.
A full security sweep was conducted before the courthouse re-opened.
Some officials say the event looks like it may have been a prank.
