A traffic cop in China who saw cracks appearing in a road prevented a potential tragedy when he coned off a sinkhole that developed in minutes.
On duty at a busy intersection in the Chinese city of Hangzhou, the policeman spots a crack appear in the road.
He tries to usher traffic away but, proving futile, he starts coning off the area where the cracks are appearing.
Minutes later a huge sinkhole opens up as the ground below collapses.
The incident was captured on CCTV, which showed drivers and other road uses cautiously moving around the hole as the cop carries on.
