The police are specifically looking for a person who must have been riding some kind of electric jet in the area at the time of the explosion.

- We have received the same information from several directions and it is on the information that we build our search for. This is what we have come to after the first technical investigation, review of surveillance cameras, interviews with witnesses and tips from the public, said police spokesman Ewa-Gun Westford, to SVT News Skåne, on Tuesday afternoon.

"Of course, we do not want to go too deep into exactly what we need, so as not to stain any witnesses we have left to hear," says Ewa-Gun Westford.
