Deputies arrested two men and one woman they believe are behind a robbery spree, but officials are still looking for one more suspect.
Investigators say the crooks hit up a gas station and a fast food restaurant Tuesday morning. Then at around noon deputies say the suspects robbed the Family Dollar on Greens and Imperial Valley near the Beltway in north Harris County and even took purses and wallets from the customers inside.
A witness tipped off police who were able to catch and arrest three of the four.
Police are looking at surveillance video from the three robberies to track down the fourth suspect.
