A Michigan man, who claimed to have a bomb with him, drove his truck into the U.S. Coast Guard Station on Lake Michigan early Sunday morning.

The man who remains unnamed, but according to CNN, is 34-years-old, drove his truck through the fence and onto the Grand Haven Coast Guard Station. After breaking into the station, the man supposedly told Coast Guard personnel there a bomb was in his truck. No bomb was found at the scene, but officials were still investigating the area.

No Coast Guard or other personnel were injured during the incident, partially thanks to a phone call intercepted by an Ottawa County dispatcher, according to the AP. The intercepted call was allegedly from the driver of the truck who stated during the call he had a bomb in his truck and planned on blowing up the Grand Haven Coast Guard Station.

Senior Chief Petty Officer Justin Olson said, according to MLive, the phone call allowed the station to enact their “in-place bomb threat procedure,” which “assured the safe evacuation of all” within the station. “We would like to thank the Grand Haven Department of Public Safety and our other partner agencies for their assistance and quick response to the incident,” said Olson. 

A report from the Grand Haven Department of Public Safety stated, according to the New York Daily News, “The incident was initially investigated as a potential act of domestic terrorism due to the circumstances.” The report then claimed the investigation had so far revealed no link to any foreign or domestic terrorist organizations.

The Grand Haven police have also indicated the man is a suspect in an Oceana County house fire. The home supposedly belonged to the driver. All investigations are currently ongoing.
