The Kielbasa Posse.
The Philadelphia Polish Mob, known as the Kielbasa Posse, are a Polish American organized crime group operating from the Port Richmond area in Philadelphia. Named after a type of Polish sausage, the gang is made up of Polish immigrants living in Port Richmond, Kensington, North Philadelphia, Northeast Philly, Bucks County, and South Jersey, as well as second-generation Polish Americans.
The gang moved into territory occupied by Irish, Russian, and Italian Mafia outfits, namely the trafficking and dealing of Ecstasy, and are said to have moved into bookmaking and loansharking operations as well. They would meet several times a week at a local Polish bar and although they have a tough and fearsome reputation, they are said to be very polite and gentleman-like to local citizens and do not start fights unnecessarily. They do not have a good relationship with the K&A Gang who controls most of Northeast Philly, due to the fact that the Northeast is predominantly Irish. According to local residents, they are not well known and the older Polish residents of the neighborhood choose to ignore the existence of the gang. From Wikipedia.
