Dramatic surveillance video has emerged from China showing several people falling into a huge hole as the pavement beneath them suddenly opens up.

The incident took place at a bus stop in Heilongjiang Province on Saturday where four people dropped directly into the hole while another woman can be seen trapped on a steel structure just below the surface of the pavement.

The footage shows a group of bystanders attempting to rescue those trapped inside. After a few minutes, they had managed to claw out the unlucky few who fell down. It has been reported that the hole measured ten square metres and was two metres deep.
