PHILADELPHIA (AP) — A second Philadelphia mobster has pleaded guilty in a federal racketeering case that also names alleged boss Joseph Ligambi.

Martin Angelina pleaded guilty in federal court Wednesday to operating illegal poker machines and attempting to collect loans through extortion. He faces a December 3 sentencing.

Angelina is the second alleged mobster to plead guilty in a racketeering and illegal gambling case that names a dozen other reputed mobsters. Gaeton Lucibello pleaded guilty last week.

Prosecutors say Ligambi headed Philadelphia’s La Cosa Nostra family and attempted to make illegal gambling earnings appear legitimate.

Trial is set in October for nine of the defendants, including Ligambi and alleged underboss Joseph Massimino. Trials have yet to be scheduled for three others.
