Outrageous U.S. radio personality Anthony Cumia has been fired for making "hate-filled remarks" on social media.

SiriusXm bosses have axed the Opie and Anthony host after he posted a series of racist remarks on Twitter earlier this week (beg30Jun14).

A statement from Patrick Reilly, the senior vice-president of communications at the satellite radio company, reads: "SiriusXm has terminated its relationship with Anthony Cumia of the Opie & Anthony channel. The decision was made, and Cumia informed, late Thursday, July 3 after careful consideration of his racially-charged and hate-filled remarks on social media.

"Those remarks and postings are abhorrent to SiriusXm, and his behavior is wholly inconsistent with what SiriusXm represents."

Defiant Cumia has since taken to Twitter.com to blast his former bosses, writing, "Sirius decided to cave and fire me. Welcome to bizarro world. Fired for s**t that wasn't even on the air & wasn't illegal."

The posts that landed him in trouble revolved around an alleged attack - Cumia claimed an African-American woman targeted him while he was out and about in New York City.
