Police smash windows in frantic bid to save boy accidentally locked inside car

Gold Coast Police have had to smash the window of a four wheel drive to save a four-year-old boy who was locked inside.

His mum says the BMW automatically locked when she left the key inside as she was about to take her child to lunch.

The pre-schooler had been locked inside for nearly 20 minutes with the sunshade half open.

As the boy's mother peers in, a senior constable tries to unlock the car.

Police used wire with a porcelain tip to shatter the brand new BMW's windows.

As the door opens, the boy cries out for his mum.

Paramedics assessed the child, who was physically fine.

In Melbourne, an eight-year-old wasn't so lucky.

He's now in a serious condition in hospital.

The temperature inside a car can be up to 40 degrees warmer than outside.

The advice for drivers is to always keep your keys on you.

"Every moment that a child is left in a warm car can cause serious internal injury and potentially death," Lauren Ritchie said.
