A teenage boy who fell an estimated 40ft through a warehouse skylight onto a concrete floor was lucky to survive, according to doctors.
Mackenzie Cooper is still recovering from his injuries in Leeds General Infirmary a week after his fall in Dewsbury last Saturday.
The 13-year-old suffered a jaw broken in two places, a broken bone in his face, a badly broken wrist, a fracture above his knee and a punctured right lung.
After he fell he managed to get up and open a shutter at the warehouse and get help.
A fire crew had to remove locks on a gate to access a yard where he was drifting in and out of consciousness.
Mum Charlotte Butterworth posted photos on Facebook as a warning to others not to risk their lives climbing onto warehouses or derelict buildings.
She said: “I wouldn’t normally post something personal on Facebook like this but I feel it is necessary to warn others.
“Children don’t understand how dangerous this is - it is their families who have to live with the consequences.”
Charlotte, of Cleckheaton, added: “On Saturday I got the call to say my child had fallen through a roof. In actual fact he had fallen 40ft through a building roof onto a concrete floor.
“Rushing to be with him I expected the worst. Mackenzie is lucky to be alive to say the least.”
She added: “By some miracle he survived the fall and his injuries could have been a lot worse.”
Mackenzie has underdone surgery on his wrist and requires a second operation.
“He also had a metal plate put into his jaw and will be on a soft diet for six weeks.
“I’ve chosen to put this on Facebook as I know friends have teenagers and it seems entering warehouses/derelict buildings is the in thing.
“Children don’t realise the dangers - Mackenzie had been warned numerous times.
“Please show these pictures (to your children) as it can happen to them. They are not invincible and you might not be as lucky as me and my child.
“The reality is I might of been planning his funeral this week.”
Charlotte said it wasn’t yet clear why or how her son had climbed onto the roof of the building which is located behind Sainsbury’s petrol station in Dewsbury.
“He doesn’t say sorry a lot but he said ‘sorry mum’ to me when I saw him in hospital,” she added.
“He told me that everything felt like a dream after he fell. He said he won’t be going on buildings again.
“We are hoping that he can come home from hospital today. He is having a second operation on his wrist as they need to put in some wire.
“The doctor said he was extremely lucky to be alive after falling 40ft.”
Mackenzie lives with his mum Charlotte, stepdad Steven and his younger brothers Mason, seven, and Theo, four.
Mum Charlotte said Mason had been distraught to see his older brother so badly hurt.
“He was heartbroken when he saw him,” she said. “He was sobbing.”
