It was during Wednesday that police were called to Nynäsham, where the ferry was in port, as three women, along with a child, barricaded themselves in a cabin on Wednesday morning.

Insertion force had to get into the cab with the help of saws

Hours later, emergency services were alerted to the scene that it was burning inside one of the cabins. During Wednesday afternoon, the police's intervention force got into the cab, using a circular and chainsaw.

The women were arrested and the child was taken care of by social authorities. Police launched a preliminary investigation into serious illegal threats. On Thursday, police announce that an investigation is ongoing.

Interrogated during the day

Interviews with those arrested will be held during the day and technical examination in one of the ship's cabins will be conducted during the day.

Yesterday's incident is classified, among other things, as grossly illegal threats, the police write on its site.
