A cab driver was robbed at gunpoint early Wednesday morning by a group of men he gave a ride to, police say.

Police said the robbery took place around 1:50 a.m. at a Shell station at Interstate 35 and Rittiman.

Three men got into the cab at an apartment complex, then one of them pulled out a gun as they were getting out, police said.

Investigators also said one of the men hit the driver with the gun.

Police are looking into whether there was surveillance video in the cab that could give them a better description of the suspects.
