Jack, who lives only a short distance from Stena Recycling, has been worried about the fire.

- You do not want to risk anything.

We did not know if we should release the animals and if the smoke from the plastic will affect, says Jack.

Preliminary investigation initiated

The police have initiated a preliminary investigation, but it is still unclear when the technical investigation of the site can be carried out.

In the investigation, the police will investigate whether there has been a crime at the site or if the fire was caused by another cause.

When can the preliminary investigation be completed?

- It is difficult to comment on time. It can take anything from a week to a month, says Mikael Hedström, press spokesperson for the Gävleborg police.
