The family of a firefighter who was among three killed in a horror blaze in Bicester have paid tribute - describing him as 'the true definition of a hero'.

Martyn Sadler, 38, died after a fire engulfed Bicester Motion - a former RAF base - alongside firefighter Jennie Logan, 30, and businessman David Chester, 57, last Thursday.

Mr Sadler was a firefighter for Oxfordshire County Council’s Fire and Rescue Service but also worked with the London Fire Brigade.

Two other firefighters suffered serious injuries and are in hospital in a stable condition, Thames Valley Police said.

In an emotional tribute, Mr Sadler's grieving family said he was 'born to be a firefighter'.
