Dramatic footage has emerged of firefighters rescuing a toddler who got locked in a self-service bank in China.

The video, filmed in Zhenjiang, Jiangsu Province earlier this month, shows the child locked behind a glass door while his mother is comforting him from the outside.

A firefighter can be seen using a crowbar to open the door and set the child free.

According to local media, the child walked into the self-service bank as someone walked out of it.

It reportedly took an hour in total to rescue the child.
