Second gas leak being investigated

No-one is living in the apartment block on the Portmore Road in Portstewart but there are two shops below.

The owner of one of the shops said two people went to hospital after feeling unwell but were given the all clear.

It is part of the HSENI's ongoing investigations into the deaths of two teenagers in Castlerock a week ago.

Earlier on Tuesday police searched premises at the centre of the Health and Safety Executive alert connected with the death of the two teenagers.

They took a number of items away for examination.

On Monday, the HSENI urged anyone who had work done by George Brown, of 'The Calor Shop' in Coleraine, to switch off all gas appliances.

Mr Brown has not commented publicly since the advice was issued on Monday.

'The Calor Shop' is an entirely separate legal entity to Calor Gas (NI) Limited.

The HSENI also revealed a liquid petroleum gas appliance in the flat where the teenagers died was defective.
