At least one person has died after a suspected sword-attack at a school inside a shopping mall in Finland.

Finnish police say nine people have been hurt – two seriously – after the incident at Savo Vocational College, temporarily located inside the Hermann mall, in the eastern city of Kuopio.

The alleged assailant – the tenth injured person – has been arrested after police used firearms to apprehend him.

Witnesses claim he was armed with a long knife or a sword.

One onlooker, named in reports as Roosa Kokkonen, told MTV news how the suspect pulled out a sword from a bag he was carrying.

The violent attack triggered a huge response from the police and emergency services

"Then he started stabbing as many as he had just hit. A classmate was one of them."

Another woman was reportedly seen bleeding from her hand.

Earlier reports had claimed the suspect was armed with a gun.

The victims have been rushed to hospital.

Officers have now cordoned off the building.

A police spokesperson said: “According to current information, the incident in Kuopio occurred at the premises of the Savo vocational school located in the Herman shopping centre.”

The mall is housing the college while a new campus is being built, reports claim.
