At least two people have been injured in Norway’s capital city as they were struck by an ambulance stolen by an armed man who was injured when police opened fire to stop him.

Officers said those struck by the ambulance included a woman with a pushchair and an elderly couple. The woman and her baby were taken to hospital.

“We are in control of the ambulance that was stolen,” Oslo police tweeted. “Shots were fired to stop him. He is not in critical condition.”

Police also said they were looking for a woman who “looks drunk” and may have been involved in the incident in north Oslo.

Anders Bayer, a spokesman for Oslo University Hospital, confirmed to Norwegian news agency NTB that the ambulance was stolen by an armed person.

Three employees in the vehicle when it was stolen were unharmed, he added.

The Aftenposten newspaper published a photo showing a man wearing green trousers lying next to the vehicle surrounded by police officers. Another photo showed a handcuffed man, flanked by police, walking towards an ambulance stretcher.

A witness told the newspaper he saw “the ambulance driving at high speed toward me … and right behind a police car”.

“I heard several shots,” Omar Khatujev told Aftenposten.

The yellow ambulance smashed into a house wall with a police car ramming into its rear.

Therese Ramstad, another witness, saw the incident from her ambulance and told Norway’s TV2 channel that she thought the vehicle had been hijacked.

“I saw how police officers took the baby in their arms and tried to comfort it. It was crying,” she said, adding that a woman and the baby were driven to hospital in police cars.

“It is too early to say whether this is terror-related, but we are investigating broadly and fully,” police said.
