The parents of a university student who died after he inhaled a 'fatal quantity' of carbon monoxide while staying in a remote aristocrat-owned holiday cottage have called for 'dangerous' portable gas heaters to be banned.

Tom Hill, 18, was preparing to take a bath when he succumbed to the highly poisonous gas leaking out of the 'lethal' device at an 'idyllic' rental home in the Scottish highlands.

An inquest which took place this week, some 10 years after his tragic passing, heard the bathroom where the cabinet heater was kept was 'simply too small' - but the warning informing users of this was not obvious.

While a coroner concluded that while Tom's death in October 2015 was accidental, he said there is a risk of future deaths being caused by such devices.

'Proud' parents Jerry and Alison Hill have now called for more awareness to be raised on the dangers of carbon monoxide and portable gas heaters.
