A man watching a half-marathon in Emerson, New Jersey, on Sunday allegedly dropped his pajama pants and began masturbating.
Dozens of runners witnessed the act, the Daily Voice reported, leading police to arrest 55-year-old Thomas Pantuso afterward on a street corner.
“There were several people who saw him, so there are several witness accounts,” Emerson Police Capt. Michael McDermott told the newspaper.
Pantuso was taken to a local hospital for evaluation.
Hundreds competed in the 13.1-mile event, known traditionally as the Run the Reservoir, with proceeds benefiting pediatric cancer research.
Runner’s World noted that the alleged offense appears to have occurred about a mile into the race, meaning that the runners had about a dozen miles to go after witnessing the incident.
HuffPost has reached out to Emerson police for an update.
