A Jersey City man originally suspected of having sex in public urinated on a fingerprint machine at the Hoboken police station this week, officials said.

Police found the man, and a Jersey City woman, on a stoop at Jackson and Fifth streets, Hoboken, after receiving a report of adults having sex in public, according to reports.

When police arrived at the address at about 7 p.m. Tuesday, they found Jeffrey Mahon, 43, and Shiela Slaten, 59, who said they had just been sitting on the steps and were not doing anything sexual, according to reports.

No one in the area wished to file any complaints, police said.

However, when police checked the names of the suspects, they found that both had outstanding warrants.

Mahon had three warrants from Hoboken and Slaten had a warrant from Jersey City, according to reports.

Police arrested both and took them to the police station for processing.

At the station, Mahon stood up from the chair where he was handcuffed and urinated on the fingerprint machine, officials said.

He was subsequently charged with criminal mischief, reports said.

Mahon was taken to Hoboken University Medical Center to be evaluated and cleared for incarceration, officials said.

He was taken to the Hudson County jail on Wednesday, officials said.
