HARRIS COUNTY, Texas -

Deputies say a GPS tracking device in a stolen cell phone helped track down four men believed to be responsible for an armed robbery at an AT&T store in north Harris County.

Harris County Sheriff's Office deputies said Donte Valentine, 19, Jakelvin Gilliam, 20, Jeremy Gibson, 18, and Johnnie Isabelle, also 18, stole several mobile phones from the AT&T store at 7025 E. FM 1960 shortly before noon Tuesday.

The suspects were armed and had their faces covered, according to witnesses.

Deputies tracked the suspects to an apartment complex in the 14900 block of Bellows Falls. All four were charged with aggravated robbery.

Stolen merchandise, firearms, and clothing worn in the robbery were all recovered inside a vehicle that was reportedly used in the hold up.

Investigators are also trying to determine if the four men are responsible for other similar robberies in the area.
