An explosive device was discovered at an ATM in London’s Financial District in what police say was a “bombsight” cash robbery.
The device was found at a home in the 8500 block of East 5th Street, near Central Park, police said in a statement.
It was not immediately clear what the device was for.
It comes as the number of bombs found in the United States continues to grow and the number in Europe has surged, officials say.
More than 4,500 people have died in bomb attacks since 2001, according to a tally by the Washington Post.
In Europe, the latest deadly attack occurred Saturday in the northern city of Copenhagen, when a man who police believe was a suspect in the November 2013 bombing of a Berlin Christmas market opened fire, killing eight people.
Authorities are searching for a possible second attacker.
Police said in the statement that the suspect had been arrested on a “serious terrorist charge.”
The bomb squad responded to the scene and determined that the device “was not a terrorist device,” a police statement said.
The devices were being searched and the investigation is ongoing, police added.
