University of South Alabama police arrested a Bay Minette man Friday afternoon after he was spotted masturbating inside Marx Library, school officials said.

Around noon police responded to a report of a man exposing himself in the campus' main library, said USA spokesman Bob Lowry.

"It is my understanding that he was masturbating," Lowry said.

The man had fled before officers arrived but was apprehended a short while later.

Police charged Kalvin Andreas Snowden, 39, with one count each of indecent exposure and attempting to elude police.

The arrest marked Snowden's fifth indecent exposure charge in southern Alabama since 2007, according to court records.

Snowden pleaded guilty to four indecent exposure charges in Baldwin County, including three reported incidents in or very near Faulkner State Community College.

According to a deposition written by a Bay Minette police officer and filed in Baldwin County District Court, Snowden walked into the college's administration building around 10:30 a.m. on Oct. 1, 2007. He went to the second floor and exposed his genitals three times.

Before his arrest he masturbated in front of a student in one of the building's hallways. He got within 5 feet of her.

"Each time he walked away he turned his head and looked at her," while exposed, investigators said. "This conduct frightened and alarmed the student."

In 2009 he pleaded guilty to the charge and a separate indecent exposure reported at Faulkner State Community College in June 2009.

He pleaded guilty to two other indecent exposure charges in 2010.
