It is eight years today since four men were killed following the partial collapse of Didcot Power Station.

Demolition workers Michael Collings, Ken Cresswell, Christopher Huxtable and John Shaw were killed on February 23, 2016.

It took more than six months for their bodies to be recovered, prompting criticism from their families at the time.

And today an investigation by Thames Valley Police and the Health and Safety Executive is no further on.

Thames Valley Police said the investigation team, which was put in place immediately after the collapse at Didcot, continues to investigate offences of corporate manslaughter, gross negligence manslaughter and health and safety offences.

Steve Wright was watch manager of the Didcot fire crew who first responded after the boiler house collapsed at the disused coal-fired plant which was being prepared for demolition.

He tweeted: "Eight years since attending this incident on the first fire applicance, tragic and testing incident, one I know still affects the Watch."

He said by coincidence the Watch photo was taken on that morning with part of the power station in the background.

Ben Snuggs, deputy chief constable of Thames Valley Police, said: “As always our thoughts remain with the families of Michael Collings, Ken Cresswell, Christopher Huxtable, and John Shaw following the loss of their loved ones.

“Thames Valley Police, together with the Health and Safety Executive, remains totally committed to rigorously investigating the collapse, and I am very conscious of the time it is taking to investigate those circumstances.

“We maintain regular contact with the families, and continue to provide updates and support through our dedicated family liaison officers and investigation team.

“This investigation is significant and complex with vast amounts of witness, digital and physical evidence, and we continue to make good progress with further suspect and key witness interviews.

“We are also in close liaison with the Crown Prosecution Service, and continue to provide appropriate updates to key stakeholders and interested parties."

He added: “It is our responsibility and duty to investigate thoroughly, following all reasonable lines of enquiry and we will do everything we can to provide answers to the families.”

Duncan Rudall, CEO of the National Federation of Demolition Contractors (NFDC), said: “Eight years have passed and there has been little resolution for the families of Michael Collings, Ken Cresswell, Christopher Huxtable, and John Shaw, who sadly lost their lives because of the Didcot Power Station collapse.

"All of us expected that the subsequent investigation would provide much needed answers.

"Unfortunately, closure has yet to be forthcoming, but in any incident of this nature, we must remain patient and trust the process, to ensure investigations are carried out properly and thoroughly.

"Only then can we ensure the outcome is the correct one and a similar tragedy is avoided in the future.”

Speaking two years ago on the eve of the sixth anniversary of the tragedy, Gail Cresswell, widow of Ken who was 57 when he was killed, questioned why ‘no one has been brought to task’.

She said: "The demolition industry needs answers to what went on at Didcot so that no other families are in his position again.

“Ken should be home with his family who love and miss him dearly; not laid on that hill. No one has been brought to task.

“Month after month, year after year, we're told again and again 'still no updates' by the family liaison officer.

She added: "It would be too awful if something similar happened while we're waiting [for the investigation to conclude] and another family has to go through what we're going through.”
