“The bomb squad has scanned the area and has not encountered any dangerous objects,” said Östersund police spokesperson Helena Hroh to the TT news agency.
The station was cordoned off and all rail traffic to and from the station was shut down during the day after the bomb threat was called into to the SOS Alarm emergency services at 9.15am on Monday morning.
According to the man, the bomb would “go off within two hours” after his call.
Bomb technicians and a bomb-sniffing dog were sent to Östersund by helicopter from Stockholm, a distance of some 460 kilometres.
Meanwhile, traffic in the centre of town near the station came to a complete standstill, as experts investigated the scene.
Just before 7pm, the police confirmed that the area was safe and the cordons were lifted.
The person suspected to have called in with the threat has been arrested.
“We have a man in his early 20s who is now arrested. He is suspected of making an aggravated false alarm,” said Hroh to TT.
Hroh gave no further details concerning the man’s arrest, and would not confirm how the man was tracked down by police.
Police are expected to release more information soon.
