A 62-year old contractor was killed on Saturday afternoon at the Tunbridge Wells Marks and Spencer branch.
According to Kent police Philip Dodd was declared dead at the scene on Calverley Road. The case is being treated as a work-related unexplained death.
Mr Dodd was a widower who lived in Horley, Surrey. His family have been informed.
He was found dead in a staff area of the shop where he had been working, according to local police.
An M&S spokesperson said: “There was tragic incident at the Tunbridge Wells store on Saturday and our thoughts are with the family concerned.
“We are now concentrating on doing all we can to assist the emergency services with their investigation and as such are unable to comment any further at this stage.”
A spokesman for Kent Police said police were called just before 3.30pm. He continued: “There was no need to evacuate the store and no members of the public were involved or affected by the incident.”
A post mortem is expected to be carried out later this week.
A spokesperson for Tunbridge Wells County Council said Mr Dodd was working in the store, but not an employee of Marks and Spencer. They added that the council health and safety officer is working closely with the police.
