Two Treated In Hospital After Explosion At Flat
Two people are being treated in hospital after an ''explosion'' at a flat in West Dunbartonshire.
Emergency services were called to Burn Street Lane in Bonhill at around 2.45pm on Friday.
Police Scotland said it received calls describing an explosion and images posted on social media showed the wall and roof of the first-floor flat largely destroyed.
One man is being treated for burns and another for smoke inhalation.
Police and the fire service are investigating the cause of the fire and some nearby properties have been evacuated while gas mains in the area are checked.
A Police Scotland spokeswoman said: ``One man is being treated at Glasgow Royal Infirmary for burns and another was taken to the Royal Alexandra Hospital in Paisley to be treated for smoke inhalation.
''Emergency services remain at the scene and a joint investigation with police and the fire service is to be carried out.
''West Dunbartonshire Council has set up a rest centre for those evacuated from their homes.''
Gas engineers carried out checks in the area.
A spokeswoman for Scottish Gas Networks said: ''We were called out by the emergency services to reports of an explosion in Burn Street Lane, Bonhill this afternoon.
''Our engineers attended quickly, carried out safety checks and have now left site.''
A West Dunbartonshire Council spokeswoman said: ``We established a temporary rest centre within a nearby early learning centre to accommodate residents and provide warm drinks.
''Accommodation has been provided for those directly affected and we will continue to provide support throughout the weekend for anyone who needs it.''
The 26 year old was first targeted in Briarscroft Road.
Euan Johnston was shot in his car last month.
The family of three crash victims took their case for the 59-year-old to be put on trial to the Appeal Court in Edinburgh earlier this year.
