The Croydon Borough commander has paid tribute to the bravery of the two police officers involved in the South Norwood fire rescue.
"The professionalism and bravery of DS Woollard and DC Pryce was truly outstanding. They showed what the Metropolitan Police is all about - keeping our communities safe - and they put aside any concern for their own safety to make sure that the people inside those flats got out safely. Thanks to their quick thinking and actions a tragic disaster has potentially been avoided."
