POLICE have released CCTV video to assist in identifying a man who they believe may have information about a suspicious fire in Hackett on Sunday. 

They say that at about 4.30am, ACT Fire & Rescue attended a fire at an administration building on Maitland Street. The building is shared between Blue Gum Community School and three other community groups.

Firefighters extinguished the blaze, however the building sustained significant structural and smoke damage – the estimated cost of the damage is more than $50,000.

Around the time of the fire, a nearby tree was also set alight.

Following an investigation, police believe the fire was deliberately lit and have released CCTV footage of a man entering the building with a bike at about 4.15am on Sunday. They believe he may have information in relation to the incident.

Five other people were seen to have been in or around the buildings in the hours before the fire.

One man was seen walking between buildings at the premises. He was wearing a maroon sweater, dark pants, and was carrying a large blue backpack.

Following this, a group of four people (possibly teenagers with one carrying a basketball) also walked between the buildings.

These five people are urged to contact police as they may be able to assist in the investigation.
