Police were looking for a fourth suspect after a robbery at a Verizon Wireless store in east Houston Wednesday morning.

Investigators said four men drove a car into a Verizon store on East Freeway near Federal Road early Wednesday morning.

An officer, who was patrolling the area, spotted the robbers when they ran into the glass windows that line the front of the store. When the officer noticed the suspects, the four took off.

Police had three of the suspects in custody Wednesday. Officers set up a perimeter and sent out helicopters to search for the fourth man.
