After responding to a "shots fired" call last night at Grinnell Street and Acushnet Ave, New Bedford cops found no one who had been shot.   They did find an 18-year-old standing in the street yelling.   During a chase through the Bay Village housing complex, the teen tossed a loaded .22 caliber semi-automatic handgun.  After a short struggle, that's when they arrested Luis Rafael Class.

Police also found a round of ammo in Class's pocket.  He was charged with unlawful possession of a firearm, carrying a loaded firearm, unlawful possession of ammunition and resisting arrest.   It's not clear if Class was firing the shots at someone or something in the area.
