An amateur treasure hunter's first foray into "magnet fishing" ended with him hoisting up an Uzi and four other loaded guns from a Massachusetts pond.

The unnamed man had used a rope attached to a magnet to trawl Pillings Pond, a large body of water in Lynnfield, 13 miles north of Boston.

The man called the Lynnfield Police Department after he hauled up a loaded Uzi submachine gun, The Daily Item reported.

When an officer asked the man to dip the magnet again, he pulled up a loaded .40 caliber Glock handgun, a Colt Cobra revolver, a rusted revolver, and a semiautomatic handgun.

A Massachusetts State Police ballistics unit has taken the weapons for further analysis.

An amateur treasure hunter lowered a magnet into a Massachusetts pond to search for trinkets, but instead hoisted up five guns, including an Uzi submachine gun.

Using a strong magnet on the end of a rope, the unnamed man pulled up a loaded Uzi submachine gun from Pillings Pond in Lynnfield, 13 miles north of Boston, The Daily Item reported.

He later found a .40 caliber Glock handgun, a Colt Cobra revolver, a rusty unidentified revolver, and a semiautomatic handgun.

The man told the newspaper he had just taken up the hobby — known as "magnet fishing" — after becoming inspired by a documentary about European fishermen hunting down World War II treasures in French canals.

The man called the Lynnfield Police Department upon finding the Uzi.

Officer Patrick Curran went to the pond and identified the Uzi as genuine and loaded before asking the man to lower his magnet again to see what else he could find.

The man then pulled up the four other loaded weapons.

"In my more than 35 years on the force, I've never seen anything like it," Lynnfield police Capt. Karl Johnson told the Daily Item. "It's a little strange."

Lt. Thomas Ryan, a spokesman for the Massachusetts State Police, told The Daily Item that a dive team and members of the firearm-identification and crime-scene units also attended the site.

In a similar incident, in July 2018, a British man hoisted a Mac 10 submachine gun out of a London canal while magnet fishing.
