HOUMA, La. (AP) — Authorities in Houma say they found weapons, phony law enforcement badges and fake bombs at a residence where a 61-year-old man was arrested.

Monday's discovery at an apartment complex led to a six-hour evacuation of about 40 people from four buildings.

The Courier reports that the investigation was launched by the U.S. Secret Service after agents learned a man had bought counterfeit badges and credentials that represented him as a federal agent. The Terrebonne Parish Sheriff's Office said federal agents and deputies found several hundred counterfeit documents, badges and credentials.

Michael Hebert, a resident of the complex, was booked with multiple charges including 19 counts of possession of a firearm by a convicted felon and 10 counts of unlawful possession of fraudulent documents.
