For the third time this summer, University of Michigan police arrested a man for masturbating in public on campus, officials said Monday.

Two people walking in The Diag Sunday night about 10:45 p.m. flagged down police officers in the area and notified them of a man who was making inappropriate comments to them, U-M Police spokeswoman Diane Brown said. The man reportedly made lewd comments to the pedestrians and they ran away from him.

While on patrol, officers spotted a man masturbating in bushes near Mason Drive and North University Avenue who matched the description given by the pedestrians, Brown said.

It’s the third such arrest on campus this summer. On June 16, a 52-year-old man was arrested during a screening of Skyfall at the Ann Arbor Summer Festival. The next day, a 46-year-old man was arrested for masturbating while riding his bike through The Diag.

Brown said the man was placed under arrest after officers found him Sunday.

“His clothing was around his ankles,” she said. “I’m not sure if anyone saw it other than the police.”

The police report did not say the man was intoxicated and no drugs were found on him, but possible drug paraphernalia was found in the area of his arrest.

He’s been released and is awaiting charges, pending warrant approval from the Washtenaw County Prosecutor’s Office.
