A Chinese boy who fell out of his third floor window ended up with his head wedged in the narrow gap between two buildings.
The 12ins (30cm) gap was too narrow for rescuers to enter and the boy continued to slip downwards as he struggled to free himself, reports China News Network.
Rescuers worked with drills for five hours to widen a ventilation shaft before finally freeing him without serious injury.
"I heard a muffled bang, and looked out to see a boy stuck between the walls," said neighbor Mrs Wang, in Guilin, Guangxi province.
Firefighter Fu Canming said: "We could only touch the boy through a small ventilation shaft, and we decided to enlarge the shaft and pull out the boy that way.
"My arms were totally paralyzed from the continual drill vibrations, but the boy's screams and cries squeezed our hearts so we carried on."
Medical staff set up a drip to keep him hydrated during the rescue and he did not suffer any serious injuries.
After five hours of drilling, the ventilation shaft was finally big enough to pull out the boy.
