The accident occurred just before 7 pm on Saturday.
A taxi bus and a car collided at the intersection between southern Skeppsbron and Brodingatan.
- It is very slippery on the site.
There is blank ice in the whole of central Gävle, black ice, but I do not know if that was the cause, says Johan Melin, internal commander at Gästrike rescue service.
Ambulance and rescue services went to the scene.
One or two people were taken to hospital.
- It was a bit unclear, but it's about minor injuries, says Melin.
Anti-slip measures are now underway in Gävle.
At 19.40, the rescue service and ambulance were ready on the spot.
