A possible military explosive training device washed ashore on a Florida beach early Sunday.
The Broward County Sheriff's Office said a deputy on patrol discovered the device on the beach in Lauderdale-By-The-Sea, about 30 miles north of Miami, at 2:30 a.m. Sunday.
"BSO deputies secured the area around the item and closed off a small section of the beach," the sheriff said in a statement.
The device had the word "inert" written on it, but authorities on the scene called a bomb squad and the Air Force "out of an abundance of caution."
It was "determined that the sea mine was safe," and it was removed from the beach, the sheriff's office said. The beach was reopened.
The origin of the device remains unclear.
