Police evacuated a station on the Stockholm underground late on Thursday, after a suspicious item was spotted on the platform, eventually proving to be a hoax, the Stockholm police said on Friday.
Bomb disposal experts summoned to the scene destroyed the object, which appeared to have been made to look like a fake bomb, a Stockholm police spokeswoman said.
The Kungstradgarden Station is the end station on one of the Swedish capital's underground train lines.
No threats have been reported in connection with the incident. Stockholm police were treating it as a deliberate hoax and a case of "gross nuisance alarm".
Security in the Swedish capital has been elevated since a suicide attack Dec 11, this year, when a 28 year old man was killed in a blast. The dead man, who sent a threatening email just minutes before the attack, was the only fatality while two bystanders were wounded.
