NEW YORK – Most people who've done time in jail can't wait to get away. But this week, New York City authorities accused one former inmate of sneaking back in.

Yonkers resident Matthew Matagrano, 36, was arraigned in Manhattan on Saturday on charges that he impersonated a Department of Correction investigator.

Officials say that for at least a week, Matagrano used phony credentials to get into multiple city lockups, including Rikers Island and the Manhattan Detention Center, where he mingled with inmates for hours.
