Fire victim Angela Sharkey, who was critically injured in a deliberate blaze at her Helensburgh home, has been told her two children and husband died in the tragedy.

Mrs Sharkey, 46, remains in a critical but stable condition in Glasgow Royal Infirmary.

She was told husband Thomas, 55, daughter Bridget, 8, and son Thomas, 21, were victims of the July 24 fire at their home in Scott Court.

Police have launched a triple murder investigation, involving about 50 officers.

The fire broke out in the living room and quickly spread. The building had just one door and the family became trapped.

Crimestoppers has put up a £10,000 reward for information that leads to the arrest and conviction of whoever committed the crime.
