INVESTIGATORS hope to move onto the site of a massive gas explosion tomorrow in their bid to establish a cause.

Structural engineers must deem the building safe before a National Grid inspector can safely enter the property in Wrentham, near Southwold, which was severely damaged in the explosion on Christmas Eve.

Lynn Brown, 50 and 20-year-old daughter Lucy suffered burns in the explosion in Chapel Road.

The mother was flown to the Norfolk and Norwich University Hospital by air ambulance, but later transferred in a comfortable condition to the specialist burns unit at Broomfield Hospital, Chelmsford.

Her daughter was taken by land ambulance to the same hospital, but discharged over Christmas.

Stephanie van Rosse, the National Grid’s senior regional communications advisor, said: “We have not been able to enter the site and will be unable to until before Wednesday.

“The gas main has been tested but the meter has yet to be checked because of structural issues. The gas supply was cut off to the house on Christmas Eve and there is no concern of any potential leak.

“It is too early to determine a cause of the explosion until a full investigation is carried out.”

Police continue to guard the property until the structural engineer and investigator have completed work.

Meanwhile, neighbours have started a collection for the injured women.

Wrentham Parish Council clerk Angela Day said: “We are a small community and everybody looks after each other in this village. Lynn has lived here all her life.

“She has lost everything and local people would like to do something to help.”

Collection points have been set up at Fancy That fish and chip shop and the post office in the High Street.
