AN investigation has been launched after a family escaped a suspected arson attack that badly damaged their home in the early hours of Saturday.

Three fire crews from Poole were called at 2.15am to a semi-detached house in Wavell Avenue on the Waterloo estate.

Dorset Fire and Rescue Service said a mum and her 18-year-old daughter had to climb out of a first-floor window and onto the porch roof to get out after the fire blocked their escape. A man was also able to get out - nobody was injured. The victims were checked over at Poole Hospital.

A fire service spokesman said it was thought the blaze was started maliciously.

Anyone with information is asked to contact police, quoting reference 74:28. Call 01202 222222 or Crimestoppers number, 0800 555 111.
