IRWIN, Pa. — A western Pennsylvania school district is investigating pictures posted on Facebook that show a disc jockey holding up bras that students threw at him during the high school's recent homecoming dance.

Norwin School District officials tell WPXI-TV they don't know how many students were involved or whether they'll be disciplined.

The DJ, Eric Wenning, says he posted the pictures from the Norwin High School dance on his own Facebook page and says he was appalled, as were dance chaperones, when the female students started throwing their bras at him.
