Comedian Stephen Rannazzisi has admitted to fabricating a story about being in the World Trade Center during the 9/11 attacks.

Though he has said for years that he worked in one of the towers, on Tuesday he revealed that his account was false.

"I was not at the Trade Center on that day," Rannazzisi said in a statement.

He has frequently stated in interviews that he was working for Merrill Lynch and escaped from the 54th floor of the south tower, the New York Times reported.

In an interview with lolflix earlier this year, Rannazzisi said that his narrow escape encouraged him and his wife, Tracy, to move to Los Angeles, California, and make a career change from finance to showbiz.

In his apology, Rannazzisi also stated that he wished he could have erased a story told by an "immature young man."

"It only made me more ashamed," Rannazzisi said. "How could I tell my children to be honest when I hadn't come clean about this?"

Rannazzisi took to Twitter Wednesday morning to further apologize in a series of posts.

The story, he tweeted, "was profoundly disrespectful to those who perished and those who lost loved ones."
