A man remains in serious condition in hospital after being injured by a blast which ripped through a two-storey house in West Dunbartonshire.
Emergency services were called to Burn Street Lane in Bonhill at around 2.45pm on Friday after locals reported that a large explosion had resulted in a major fire at the address.
Images posted on social media showed the wall and roof of the first-floor flat largely destroyed, while fire crews worked through the afternoon to tackle the flames.
A 72-year-old man was released from hospital on Friday night after being treated for smoke inhalation, while a 32-year-old man remains in serious condition at Glasgow Royal Infirmary.
Police and the fire service are yet to establish the cause of the blaze but evacuated some nearby properties as a precaution while gas mains in the area were checked.
A Police Scotland spokeswoman said: "A 72-year-old man was released from hospital last night following treatment but another man, who we believe is 32-years-old, is still at the Glasgow Royal Infirmary and is thought to be in a serious condition.
"A joint investigation is ongoing but as yet it is too early to say what caused the explosion."
A fire service spokesman said: "We received the first of many 999 calls relating to a fire at Burn Street Lane in Bonhill shortly before 2.40pm on Friday.
"Crews from Dumbarton, Balloch and Clydebank attended and extinguished a fire in a two-storey building."
Gas engineers carried out checks in the area on Friday night to ensure the surrounding properties were not at risk.
A spokeswoman for Scottish Gas Networks said: "Our engineers attended quickly, carried out safety checks and have now left the site."
West Dunbartonshire Council set up a temporary rest centre within a nearby early learning centre to accommodate residents and provide warm drinks.
A spokeswoman said: "Accommodation has been provided for those directly affected and we will continue to provide support throughout the weekend for anyone who needs it."
