Assistant Chief Constable Dennis Murray said: “Firstly, the thoughts of everyone at Thames Valley Police remain with the two injured firefighters, their family, friends and colleagues as well as the family, friends and colleagues of Dave Chester, Jennie Logan and Martyn Sadler.
“We have now taken primacy for the incident and our major crime unit is carrying out an unexplained death investigation.
“I want to reiterate that this is currently not a criminal investigation, however, we will follow the evidence as our inquiries continue.
“The building is currently being assessed by structural engineers to understand whether it is safe to allow our officers and partners to carry out examinations at the scene.
“We will be supported by the fire service in trying to establish the cause of the fire.
“I would like to thank all of our partners who have been involved in responding to this tragic incident.”
The fire was reported at about 18:30 BST on Thursday and rapidly spread through a former aircraft hangar at the site on Buckingham Road, and a major incident was declared.
Ten fire and rescue crews were called to tackle the blaze as witnesses reported seeing black smoke in the sky.
