Two more firefighters remain in hospital in a stable condition after suffering serious injuries in the fire, which was brought under control. A police investigation has since been launched. Ten fire and rescue crews were called to tackle the blaze at about 18:30 BST on Thursday which rapidly spread through a former aircraft hangar at the site on Buckingham Road, and a major incident was declared. Thames Valley Police (TVP) has taken over the scene from Oxfordshire County Council's Fire and Rescue Service after crews had brought the fire under control and made the area safe. On Tuesday, the force said the major incident status had now been removed, with the operation moving "from a rescue to a recovery phase". Tributes have been paid by people across the UK and two plaques in memory of the three victims have been hung at the site, signed "Love from the Bicester Community". A spokesperson for the Health and Safety Executive said it was liaising with TVP on the investigation into the fire's cause. Bicester Motion said in a statement the site had worked closely with the force to "implement a phased return to work for on-site businesses". Mr Sadler and Ms Logan were also members of Bicester Rugby Union Football Club's (BRUFC), with Ms Logan playing for the Bicester Vixens.
