HARRIS COUNTY -

Deputies are searching for a masked armed robber while his suspected accomplices sit in jail.

The Harris County Sheriff's Office said a group of four men stormed into the Valero on Fairbank N. Houston and West Road in the northwestern part of the county around 2:30 a.m. Wednesday.

Deputies said the men demanded cash and items from the clerk before running off toward a subdivision behind the store.

Deputies located the three of the men in a car and surrounded the vehicle, the sheriff's office said. 

Three men were taken into custody.

All of the stolen merchandise was found and recovered in the car, according to deputies.

Investigators believe the fourth suspect lives in the subdivision. They are still looking for the man in the area.
