EMERGENCY services are still unable to enter the site of the massive factory fire in Leamington.
A worker at Leeson Polyurethanes remains unaccounted for following the huge blaze on Friday.
A police spokesman said: “Understandably, there is concern within the community in regards to the welfare of a man who remains unaccounted for following the fire in Juno Drive.
“A specialist search operation will commence as soon as it is safe to do so. However, this will be a very thorough and complex operation which may take a number of days to complete.
“Warwickshire Police are working closely with fire investigators and in collaboration with the Health and Safety Executive (HSE).
“It will not be possible to determine the cause of the fire until the site can be safely accessed and examined by investigators.
“The family of the missing man are being kept fully informed throughout the operation.”
