NEW YORK (CBSNewYork) — A retired New York City firefighter who worked at Ground Zero after the 9/11 attacks is trying to get his helmet back after it was stolen from his Long Island home.

Michael O’Connell took to Facebook on Tuesday in an effort to recover the helmet.

“This was my FDNY helmet I wore my entire career including 9/11/01,” the former lieutenant wrote. “It was stolen from my home a while back. I know it’s a long shot but if enough people share maybe it turns up or is sent back so I can keep it in my family! Thanks!”
