The blast took place at around 4am on Saturday, in the three-storey Haut Du Mont residential block owned by Andium Homes.

On Sunday, police said the rescue mission had become a “recovery operation”, with an estimated four further residents feared dead.

Justice Secretary and Deputy Prime Minister Dominic Raab tweeted: “I’m deeply saddened by the incident in Jersey this morning and my thoughts are with everyone affected.

“I commend the work of the emergency services responding and we stand ready to support in any way we can.”

– The investigation

States of Jersey Police said they would continue to investigate all the circumstances around the cause of the fatal explosion.

The investigation is being co-ordinated by the force, and involves the fire service and gas engineers working at the scene, which remains cordoned off.

Police said these examinations are likely to continue over the next few weeks.

Chief of Jersey Police Robin Smith said on Sunday: “The police service is ferociously operationally independent, I am completely independent of anyone in terms of this investigation.

“We will seek experts who are also independent, as we would do with any investigation where there is particular specialisms, be reassured this will be an independent investigation.”

Asked whether criminal activity was suspected, he said: “We rule nothing in and we rule nothing out.”

– The impact on the community

Associate Rector of the Parish Church of St Helier, James Porter, said the incident had had a “profound” impact on the community, particularly because it came days after three fishermen went missing at sea off the west coast of Jersey.

Speaking at the church the day after it held a candlelit vigil for those affected by the blast, Mr Porter said: “This has affected the community in a profound way.

“It’s a very small community in Jersey, and lots of people know lots of people, so there are lots of links.

“I think following on from the tragedy with the lost fishermen earlier in the week as well, it’s been hard for people to digest.”

Mr Porter added that he was heartened by the outpouring of donations and offers of help in St Helier, and the church would be open for anyone who needed it.
