Police, rescue services and an ambulance were alerted to Havsörnsgatan on Råslätt on several different occasions during Wednesday.
The first alarm came as early as 18.40 on Wednesday. Almost five hours later it was time again. The rescue service received a fire alarm in a detached building on the same street.
A fire alarm also went off just after one o'clock and then it burned in several different refuse rooms on Havsörnsgatan
The police suspect that the fires have been incurred and have therefore made a claim for damage through fire.
