It was 8:30am this morning during rush hour. Louis Rivera, who has been a Guardian Angel since 1982, entered a Q train at Ave. J in Brooklyn heading to Manhattan. The train car was packed except in the far corner. Louis worked his way towards the far corner and saw an elderly black man who was disheveled and sitting down. He was surrounded by piles of garbage. When Louis got to the location he saw this same man pleasuring himself with his one hand while holding a XXX rated magazine up with his other hand. At the Parkside stop of the Q train Louis told the guy to stop it and put his member in his pants. He was clearly an EDP. At the ATLANTIC AVE station the guy started pleasuring himself again. This time Louis ordered him off the train at DeKalb Ave. but riders BEWARE!
