Denton police on Sunday night responded to the fourth armed robbery since Sept. 5.
Investigators believe all the incidents may be connected to the same man, according to department spokesman Shane Kizer. In all four robberies, witnesses described the suspect as a 5-foot-8 black man wearing a cloth over his face and brandishing a handgun.
All the robberies have taken place in the late-night and early morning hours, between 11 p.m. and 1:16 a.m., according to police reports.
In Sunday's robbery, a man wearing a black cloth over his face walked into the Quality Inn and Suites in the 1500 block of Dallas Drive at about 11:50 p.m., police said. He held the clerk at gunpoint and got away with $248, police said.
A supervisor at the motel, who asked not to be identified, said security cameras captured the roughly 45-second encounter.
"The guy came in, pointed a gun — all he said was, 'Give me the money' — and the desk clerk cooperated as instructed," the supervisor said.
The first robbery occurred at about 1:16 a.m. Sept. 5 at a 7-Eleven convenience store in the 1200 block of South Loop 288. Wearing a white cloth over his face, a man wielded a handgun and ordered the clerk to empty the cash register.
He got away with about $300, police said.
At 11:09 that night, police responded to an aggravated robbery at the Corner Stop convenience store, about 6 miles away in the 3200 block of North Elm Street. Police said a man came into the store with a handgun and got away with about $200, according to a police report.
In the early morning hours of Sept. 6, a man, also wearing a cloth over his face, robbed the Super 8 motel in the 600 block of South Interstate 35E. He held the clerk at gunpoint and left with about $225, police said.
Denton police have obtained security camera footage of the incidents, but it's not good enough quality to discern the identity of a suspect, according to police Sgt. Danny Fletcher.
"There's nothing that can be gleaned from it anyway," Fletcher said. "We're still working on trying to enhance it."
No one has been injured in the robberies, and no arrests have been made, police said.
