A 50-year-old construction worker has died after falling from machinery on site in Pembroke Dock.
The self-employed construction worker has been named as Stephen John Greenaway from Telford.
A HSE spokesman has confirmed that Mr Greenaway fell from a cherry picker on the site.
Mr Greenaway was working on a Mustang Marine slipway in Pembroke Dock when the incident occurred just before 9am on 4 June.
He suffered multiple injuries and was flown by an air ambulance to the University Hospital of Wales in Cardiff where he later died of his injuries.
A Dyfed-Powys Police spokesman told Construction News the incident is no longer a police matter and the investigation has been handed to the HSE.
Mustang Marine managing director Kevin Lewis said in a statement: “This has been the most tragic of incidents we could imagine. We are a very close community at Pembroke Dock and the Port of Milford Haven as a whole, and this incident has been felt by us all.
“Our deepest sympathy goes to the family and friends of the gentleman who passed away, together with my colleagues we are all saddened by the news of his death.
“Although the gentleman was not a direct employee, Mustang Marine together with the Port of Milford Haven are working with the police and the Health and Safety Executive who are carrying out an investigation into the incident,” he added.
