Earlier this week, the cruise ship M/S Birger Jarl - now M/S Baltic - left the port in Timrå, where it had been for more than two years.
Despite the fact that the ship has a ban on use.
A preliminary investigation has been launched to look into whether the ship has been moved illegally.
A new berth for the ship was in Lunde, where an oil leak is now being investigated.
The spill is said to be approximately 30 meters long and 15 meters wide, and additional oil may have washed up with the waves.
The pipe believed to be the cause of the leak has been sealed.
The owner has been contacted
The rescue service has contacted the environmental office in Kramfors.
- It is difficult to say what the spill may lead to at the moment, but quite a lot of oil has leaked out, says Göran Sundkvist.
The owner of M/S Baltic must be notified of the release.
The rescue service and coast guard are flying drones to get a better idea of the extent of the spill.
- Emissions are not good, the coast guard will probably take over and investigate this, says Göran Sundkvist.
