Two men have been detained in connection with the deaths of a father and two children following a fire at their home.
The blaze almost a year ago led to the deaths of Thomas Sharkey Snr, 55, his son Thomas Sharkey Jnr, 21, and daughter Bridget, eight.
Their mother, Angela Sharkey, then 46, was injured in the fire at the family's flat in Scott Court, Helensburgh, Argyll and Bute, on July 24 last year.
Strathclyde Police said two men aged 36 and 49 have been detained in connection with the incident following police activity in Helensburgh this morning.
Mr Sharkey Jnr was found dead at the scene, while Bridget died on the way to Royal Alexandra Hospital in Paisley.
Six days later Mr Sharkey Snr died in Glasgow Royal Infirmary of pneumonia caused by breathing in smoke.
A joint funeral for the brother and sister was held on October 28 in Helensburgh while their father's funeral took place three days later.
