A fast food restaurant on West Berry Street has closed its dining room to late-night customers after an armed robbery last week, an employee said.

The Whataburger restaurant located at 2401 W. Berry St. was robbed about 1 a.m. Feb. 11 by a man wearing a mask and wielding a shotgun, said Lt. Paul Henderson, Fort Worth police spokesman.

A Whataburger employee said the location has closed its dining room from midnight to 6 a.m. Sunday through Wednesday in wake of the robbery, but the drive-thru remains open 24 hours a day. The general manager declined to comment about the incident.

Henderson said the man ordered everyone to get down and kicked a Whataburger employee before leaving with an undetermined amount of cash from the registers and midnight drop boxes.

The suspect escaped in a dark-colored, older-model sedan driven by another man, Henderson said.

Henderson said the same two men are suspected of robbing a RadioShack store on the 3000 block of Mansfield Highway and a Great Outdoors Sub Shop franchise in the 3200 block of Camp Bowie Boulevard.

During the other two reported incidents, one of the men entered with a shotgun, while another brought in a pistol, Henderson said. He said it was hard to determine the mens’ ages because of their disguises.

Henderson said the police do not have any definitive leads as to the identity of the suspects.
