Police are seeking the public's help in capturing two bandits who have robbed at least 16 convenience stores in the tri-state area, tossing hot coffee in cashiers' faces before grabbing money from cash registers and running.

The pair have targeted primarily 7-Eleven and Wawa stores, and the companies are offering a reward of up to $10,000 for their arrest, police said.

Many cashiers have been injured during the robberies in Pennsylvania, New Jersey and Delaware.

Police today released surveillance photos of the two robbers with the hope that someone would recognize them.

Anyone with information is asked to call the Philadelphia Police South Detectives at 215-686-3013 or 3014.
