This is the moment a seven-year-old boy cried as firefighters cut away a bicycle ball bearing ring that was stuck on his finger.

The youngster was sent to the hospital after he curiously put the metal casing on his finger but could not remove it.

Doctors unsuccessfully used lubricants and a splint before calling the local rescue team for help in Krabi, southern Thailand.

Footage shows one of the men carefully and slowly cutting the bearing ring away from the boy's finger while he was sobbing throughout the process.

The boy's parents said that their son was careless and should learn from this mistake.

The mother said: "I think it is normal for a child to be curious but they have to learn so they do not repeat the mistake again."
