A TODDLER has died after being “forgotten” inside a car in Spain -amid a horror heatwave which has reached highs of 35 degrees.

A young boy, estimated to be about two years old, was discovered in his father’s vehicle on an industrial estate in Valls, a town on the Costa Dorada, near Tarragona on Spain’s east coast.

The alarm was raised around 3pm on Tuesday afternoon before firefighters rushed to the vehicle.

When they arrived, they found the youngster’s dad beside the child with the car door already open.

They tried to revive him with help from emergency medical responders who arrived soon after.

The responders practised CPR on the toddler before discovering he had gone into cardiac arrest.

Efforts to save his life were unsuccessful – and he was tragically pronounced dead at the scene.

A police probe into the horror accident has been launched.

It is unclear if any arrests have been made yet, but police questioned the parent shortly after the ordeal.

According to police reports, the father reached his workplace at approximately 9 am and reportedly left the toddler in his car seat at the back, inadvertently forgetting about him, as covered by the Daily Mail.

A colleague reportedly made the shocking discovery about six hours later, having noticed the child inside the car while walking past on the industrial estate, and immediately informed the father.
