The Malta Resources Authority has sealed a number of pipe fittings that could be used to illegally refill cylinders at a gas facility that is under investigation.

The measure was taken as a precaution and the authority increased the number of random and surprise inspections at the facility, MRA chief executive Anthony Rizzo told Times of Malta.

No further details could be given as police were investigating.

On Wednesday, main gas supplier Liquigas said it had received evidence of illegal cylinder filling “at a third party site” and asked police to probe the matter.

Yesterday, Liquigas advised consumers to check their cylinder seals before use."Liquigas Malta genuine seals have an injection point on top, between the words ‘Liquigas’ and ‘Malta’ and a square profile rim.

"Liquigas is offering to replace any of its yellow and green cylinders, which are still unused and which have a fake seal," it said.
