A Parkton man known as the Ravens superfan “Baltimore Birdman” has been arrested and charged with three counts of sexual offense against a minor, Baltimore County Police said Thursday.

According to police, a warrant was obtained Wednesday for Gregory Hudnet, 64, of the 18200 block of Foreston Road in Parkton.

Police said a family member claims to have been sexually abused by Hudnet at multiple locations in Baltimore County between 2005 and 2008. The family member contacted authorities last month, police said.

Police said the victim did not tell anyone about the abuse until this year, and detectives began to investigate the claims when they were reported Aug. 22.

According to police, Hudnet acknowledged that he was known as the “Baltimore Birdman,” a fan who attends games in a classic purple car and wore garish purple and gold outfits to games.

He also retired from the Baltimore County Fire Department in 2008, according to police, and last held the rank of captain.

Hudnet has been charged with two counts of sexual abuse of a minor and a third-degree sex offense, police said. He turned himself in at the Towson precinct Wednesday night, and was released after posting $750,000 bail.
