The Swedish coast guard has blamed a sleeping crew member for the hard grounding of a cargoship on Sunday.

It said a criminal case has begun relating to negligence in sea traffic.

The 1,500-dwt Bonita (built 1987) went aground north of Kallandso.

"In the interrogation of the crew, a person has acknowledged that he or she has fallen asleep during his guard, which caused the grounding," it added.
