An arrest warrant has been issued for a man suspected of making bomb threats to four area Walmart locations, an official said.

Ashdown Police Department has issued an arrest warrant for William Dudley Edwards, 46, address unknown, said Ashdown Police Chief Doyle Crouch. The warrant is for threatening a bombing or fire.

There were a total of five phone calls made to the Ashdown Walmart. The caller stated there was a bomb in the store. The calls were made at 6:33 a.m., 6:35 a.m., 9:57 a.m., 10:02 a.m. and 10:03 a.m. Friday, Crouch said.

He said Edwards is also suspected of making the phone calls stating bombs were in the two Texarkana Walmart locations and the New Boston, Texas, location.

Edwards' ex-wife assisted in the investigation, Crouch said.

FBI and the Arkansas State Police have joined the investigation.

Verizon's unlawful call center helped law enforcement officials track the phone number, Crouch said.

Voice recordings matched in the incidents, he said.

A motive isn't known at this time.
