A Montgomery County personal injury lawyer has been sentenced to five years in prison and ordered to pay $3.4 million in restitution after pleading guilty to a scheme to steal multiple cases over the course of a decade from a Philadelphia law firm where he worked.

Neil Mittin, 64, formerly of Gay & Chacker, was sentenced Thursday by U.S. District Judge Michael Baylson of the Eastern District of Pennsylvania for one count of mail fraud. Mittin’s lawyer, Joseph Poluka of Blank Rome, declined to comment on the sentence.
