Police are treating a fire at a block of flats as suspicious – after the blaze was caused by a firework.
Firefighters were called to Summerhill Drive in Mastrick at just after 10.30pm on Tuesday evening after a fire broke out in a bin store.
Officers made the scene safe and helped, before leaving a man in the care of paramedics.
A Scottish Ambulance Service spokeswoman said: “We received a call at 10.48pm on Tuesday to attend an incident on Summerhill Drive in Aberdeen.
“We dispatched one ambulance and one special operations team to the scene.
“No patients travelled with us to hospital.”
Police and fire chiefs began a joint incident investigation, which continued into yesterday morning.
A Scottish Fire and Rescue Service spokesman said: “The investigation into the cause of the fire is now complete and we are treating the incident as suspected wilful fire raising.
“A firework had been set off and that is what caused the fire.
“The firework was either lit on purpose and thrown into the bin store or it was carelessly discarded.
“We are liaising with police as their invest-igation continues.”
The spokesman added: “There was a casualty treated by ambulance.
“We also treated the casualty at the scene before handing over to ambulance.”
In total nine firefighters, along with two fire engines, were sent to the scene.
He added: “Crews made sure all persons were accounted for.
“We used one hose reel jet and two breathing apparatus to extinguish.”
Detective Sergeant John Lumsden said: “We are treating this fire as wilful and would therefore ask anyone with information to please get in touch.
“Whoever did this had no idea how the fire would spread and the consequences could have been far worse. Luckily no one was injured as a result of this incident.
“Inquiries are ongoing and anyone who can assist with our investigation should contact police on 101 or Crimestoppers on 0800 555111 if you would prefer to remain anonymous.”
