Carrot-Bomb Art Project Bombs in Sweden
The carrot bombs had been placed around the city at the request of a local art gallery, as part of an open-air arts festival.
They had only been in place for an hour before police received their first call.
“We received a call … from a person who said they saw two real bombs placed outside the public library,” Ronny Hoerman from the Orebro police force, was quoted as saying by the AFP news agency.
“It was hard to tell if they were real or not. We find this inappropriate,” he said.
Mr Blom described it as a harmless stunt.
“After all, it is just carrots with an alarm clock and nothing else… this is just a caricature of a bomb,” he said.
