Yn doing drills on rollerblades now.. #NewYork #Bronx Police report: A shooter dressed in a black Spider-Man outfit chased after a man, gun blazing, while skating on rollerblades in the Bronx on Thursday, according to law enforcement sources. The masked menace was cruising along Union Ave. near E. 156th St. in East Tremont when he opened fire on his target around 6:50 p.m., sources said. The rollerblading wall-crawler fired off at least three shots. A bystander dialed 911 after a stray bullet crashed through his window and struck a wall inside his Union Ave. apartment, the police source said. Both the unfriendly neighborhood Spider-Man and his intended victim fled the scene. Police recovered a silver handgun in a nearby garbage can, the source said.
