A fire that claimed the life of a five-year-old girl in Co Roscommon overnight is being treated as suspicious.

A garda forensic team is trying to determine if an accelerant was used to start the fire.

Initial indications are that the fire was started maliciously.

The child who died has been named locally as Mari Connolly.

Her father Richard and her two sisters, aged six and eight, escaped the blaze at Termon Road in Boyle shortly before 2.30am.

The father jumped from an upstairs window with the two girls in his arms. He has been taken to hospital in Dublin with serious back injuries.

This afternoon, Mari Connolly's mother, Teresa - who has just given birth to twins - stopped by briefly to lay flowers and a photo of her daughter outside the house.

Gardai are appealing to people who may have information about the fire to come forward - 071 9662344.

A Garda forensic team is carrying out a detailed examination of the scene, which was attended by Deputy State Pathologist Khalid Jabbar.
