Firefighters freed a man's leg from a bicycle lock after his wife chained him to it to restrict his movement in northwestern China.

The video, shot in the city of Xining in Qinghai Province on April 15, shows firemen using a tool to tear down the bicycle lock that his wife locked it on his ankle.

According to reports, the couple had an argument, so the wife used a bicycle lock to lock a pan on the husband's ankle to restrict his movement.
