Four people were arrested when Edison police say they came across an armed robbery in progress at a Raceway gas station along Route 1.

News 12 New Jersey spoke to officer Michael Schwarz, who is being praised for his police work in connection with the arrests. Schwarz was on patrol when he drove up to the station around 10:30 p.m. last night.

Officer Schwarz tells News 12 New Jersey, "I observed what appeared to be an altercation, I tried to creep in there as slowly as I could... I observed the male was violently beating the attendant."

Police say two brothers, Barry and Henry James were arrested, along with Pedro Santos-Fernandez and Dasheenah Bernabela in connection with the robbery.
