New York ? Police say a man lighting fireworks has blown off his arm at a party on New York’s Long Island.

Suffolk County police say 36-year-old Eric Smith was using a 3-foot long metal tube to shoot mortars from the street near his Islip Terrace home around 5:45 p.m. Saturday.

Police believe he leaned over the device to ignite it and didn’t get out of the way before an explosive shot out of the launcher. His left arm was severed at the shoulder.

Smith was taken to Southside Hospital in serious condition while friends packed the lost limb in ice to try to save it. Police believe doctors will try to reattach his arm.
