A MYSTERY man has been hailed as a hero after helping to prevent an accident today.

At around 2pm, cars began swerving after a pair of burning jeans fell from a lorry in the middle of Montpelier Row, Blackheath.

Jean Richardson, who works at Heath Estates, watched the scene unfold from her office.

She said: “The smoke was causing absolute chaos. You weren’t sure if it was a bomb or what.

“All of a sudden this man appeared, nonchalantly walked across the road, picked it up, took it to the side of the road and stamped it out.”

She said: “He was a hero. He stopped what could have been a serious accident.”

Lee Green firefighters attended the scene.
