Bronx Firefighter Arrested for Alleged Ties to Reputed Genovese Crime Family Sports-Betting Ring

A Bronx firefighter has been busted for his ties to an alleged $2 million-a-year, mob-run gambling and money-laundering ring.

Thomas McMahon, of Ladder Co. 38 in Belmont, was one of eight men charged by Bronx District Attorney Robert Johnson with running a sports-betting ring tied to the Genovese crime family.

McMahon, 29, was arraigned in Bronx Criminal Court along with reputed mob associates Joseph Sarcinella, 77, Frank Mastracchio, 56, Dominick Totino, 44, Dominick Pietranico, 81, Bruno Travositino, 81, and John D’Ambrosio, 54.

Sarcinella — a longtime reputed Genovese mobster who pleaded guilty to running a gambling operation in 2002 — was in charge of the betting ring, which was run out of a social club and two gambling wire rooms, according to prosecutors.

McMahon took bets for the Bronx ring, created accounts and worked as a runner, picking up money and disbursing winnings, according to the DA’s office. “McMahon is close with Mastracchio. He calls him his ‘uncle,’ ” a source told The Post.

Prosecutors said the ring, which had been under NYPD surveillance, collected more than $2 million on NFL, NBA and NHL bets between December 2009 and June 23, 2011.

McMahon faces up to 25 years in prison if convicted. The seven-year FDNY veteran was suspended without pay. An FDNY spokesman declined to comment on the arrest.McMahon could not be reached for comment.
