A tanker sailing under the German flag rammed and severely damaged an important bridge in the Dutch city of Groningen on Saturday night.
No one was injured in the accident, but the consequences for traffic are severe due to the failure of the Gerrit-Krol Bridge, the city administration said on Twitter.
The police initially gave no information about the cause of the accident.
The skipper was provisionally arrested, reported the Dutch news agency ANP.
An alcohol test was negative.
According to the regional newspaper “Dagblad van het Noorden”, the ship is the 110-meter-long tanker “Bodensee” from Mannheim.
With four crew members on board, he was en route from Strasbourg to Delfzijl.
