BOSTON (CBS/AP) – Massachusetts State Police say a cannonball found by a fisherman at Castle Island was detonated Thursday morning.
A State Police bomb squad detonated the cannonball after speaking with the U.S. Navy.
The rusty, pitted cannonball may have dated to the Civil War-era. The cannonball was about 12 inches and had some unidentified black material inside.
The detonation happened at about 11:45 a.m. at Carson Beach. The detonation site was cleared by 11:58 a.m.
“(It) does not appear to have been (a) solid cast cannonball,” police tweeted. “Debris suggests it was filled with some type of material.”
By 12:08 p.m., air and road restrictions at Carson Beach were lifted.
