One of the police officers, who helped three people from a burning building in South Norwood yesterday, has described how he and his colleague became involved in the rescue.
"We just happened to be driving along the road when we saw smoke swirling in front of us, so we stopped to make sure that everyone was OK until the Fire Brigade and local police arrived. Most people had already evacuated from the surrounding flats, but we were told there were people still inside the flats above the shop. We were just concerned at getting everybody out quickly and safely. The smoke inside was very thick, but we made sure we helped everybody we could to get out, before getting out ourselves and waiting for the Fire Brigade to arrive."
