An overnight house blaze which forced a resident to escape through a back door is being treated as arson, according to police.

Three fire engines spent just under 30 minutes dealing with the fire in Wellington Street, Ipswich, after the alarm was raised at 2.30am.

It is believed the blaze was started after an item was placed through the letterbox, police have said.

It is understood no injuries were sustained in the incident.

A team of forensic officers are sifting through the damage as an investigation is launched.
