An Occupy Denver demonstrator was arrested late Saturday for “sexual misconduct” after allegedly groping a male television photographer.

Corey Donahue, a 28-year-old medical marijuana activist, was arrested at 10:20 p.m. in Civic Center park, according to three photographers who witnessed the event. Two of the photographers work for The Post.

This is Donahue’s third arrest in six weeks. Early Friday, he was arrested by Denver Police for unlawful conduct on public property and resisting arrest as police cleared the Occupy Denver camp. Last month, Boulder police arrested him for trespass during a marijuana-signature gathering drive.

On Saturday, about 10 police officers approached Donahue in the park and told him he was being arrested for sexual misconduct. He yelled and struggled before police handcuffed him.

Donahue told The Post last week that he was one of the first demonstrators to pitch a tent at the Occupy Denver camp near the Veterans Memorial west of the state Capitol.
