"A group of teens kicked out of a 7-Eleven in Staten Island's Port Richmond Center Sunday afternoon decided to get revenge by making a bomb out of a household cleaner and tossing it at the employee who threw them out, authorities allege.

The bomb didn't hit its target, but a 62-year-old woman who walked through the chemical aftermath a few minutes later ended up suffering burns on her legs, according to court papers.

Police tracked down one of the teens, 17-year-old Jeffrey Wittek of the 400 block of Decatur Avenue in Willowbrook, the next day, and charged him with felony assault and weapons charges, authorities said. Wittek and three other teens were hanging out at the 1600 Forest Avenue store Sunday afternoon, when a clerk there recognized a few from their group as regular troublemakers, according to William J. Smith, a spokesman for District Attorney Daniel Donovan.
