Three people were rescued from a fire at an Aberdeen block of flats which is being treated as deliberate.
The incident happened in North Anderson Drive at about 23:00 on Wednesday.
Four fire engines were sent to the scene to tackle the blaze, which started in a communal area. One of the people involved needed to be rescued by ladder.
Police Scotland said, after an initial review of the circumstances, the fire appeared to be deliberate.
Det Con Chris Wilson, who is leading the investigation, said: "Thankfully all the residents who were in the building at the time were evacuated quickly and no-one was hurt.
"However, this is a situation which had the potential to be much worse."
