Manager Notifies Authorities After Men Make Threats

Wharton authorities and officials with the FBI and the Texas Department of Public Safety said a man in his 50s and a man in his 20s were apparently upset with the food and service at a McDonald's restaurant in Wharton, Texas, at about 2 p.m. Thursday when they made the alleged threats.

The manager notified Wharton police about the threats, which prompted authorities to issue the statewide alert.

"Two gentlemen made threats toward blowing up McDonald's and also blowing up the Pentagon. By the time officials arrived, the men had already fled the scene. We immediately contacted the FBI, who is conducting the investigation at this point," Wharton Police Department Capt. Richard Coleman said.

Officials said the men left the restaurant in a white 1996 Ford Van with Texas license plate number 13K-C81.

The FBI said the men were of Middle Eastern descent.

Anyone who has any information on the vehicle or the men is asked to contact the Wharton Police Department at (979) 532-3131.
