The spectator who created a spectacle at a New Jersey half-marathon by dropping his pants to masturbate has been identified as 55-year-old Thomas Pantuso, according to a report.

Pantuso was taken to Bergen County Regional Medical Center for an evaluation after the incident Sunday at Eagle and Elmwood drives, Capt. Michael McDermott told the Daily Voice of Pascack Valley.

About 200 or so fundraising runners had just turned up Eagle Drive when Pantuso suddenly dropped the bottoms of his flannel pajamas and began pleasuring himself, witnesses said.

“He was standing on a corner in flannel pajamas with his shirt open and touching himself,” a witness told the news outlet. “Then he just dropped his pants.”

Witnesses fingered the alleged masturbator to police, who collared him along the 13.1-mile route, the captain said.

“There were several people who saw him,” McDermott said. “So there are several witness accounts.”

Pantuso has a rap sheet that includes a 1994 arrest in Hackensack on charges of resisting arrest and assaulting police, the Daily Voice reported.
