Oslo train station partially evacuated over suspect bag

OSLO: Oslo's central train station was partially evacuated and bomb disposal teams deployed on Wednesday morning because of a suspicious item of baggage, Norway’s news agency reported.

"A bag apparently with no owner was found next to the platform used by the airport shuttle, number 19. The area around the platform was evacuated. Therefore trains and buses do not travel in this area," railways spokesman Olav Nordli told the agency.

"Police are on the scene and taking the measures they deem necessary. The area has been evacuated... this measure does not concern the entire central station but a good part of it," he said.

Bomb sniffing dogs are on the scene, TV2 television station reported, adding that a man had got onto a bus that is temporarily replacing the train to the airport, put his baggage down and left again.

Police are looking for a man aged 25-30 wearing black with white headgear.
