An Arkansas college expelled a student and suspended his fraternity over the student's "blackface" Bill Cosby costume, which appeared in a photo on Instagram last week.

The New York Daily News reported that University of Central Arkansas booted student Brock Denton and suspended the campus Sigma Tau Gamma chapter after a photo of Denton dressed in blackface went public on Denton's Instagram feed along with the caption, "It was a bold night."

Denton wore a garish sweater and black face paint to the Sigma Tau Halloween party on Friday night, telling friends he was dressed as Bill Cosby.

The university acted swiftly when the controversial photo came to light.

“This picture is highly offensive and repugnant, and this representation goes against all we, at UCA believe in and stand for,” said university President Tom Courtway in a statement.

The national chapter of Sigma Tau Gamma issued a statement condemning the offensive costume and revoking Denton's membership.

Denton has since published a lengthy screed on Instagram attempting to explain himself. The Daily News excerpted part of the post.

“I have been sent death threats, threats to burn my house down. I am scared for my life,” Denton wrote.

“I am the farthest thing from discrimination (sic), as a matter of fact I fight for equality everyday, I’ve been writing a book for the past two years on what it really means to be a good person," he claimed.

Social media, Denton said, is partly to blame for creating a "corrupted society in regard to heated controversial topics such as this.”

“Please except my apology not because of me but because of the sake of this great nation (sic),” he said.
