How did the police officer help this child, who's just four years old? Well, he performed a well-known technique on him.Here's how the officer performed the Heimlich manoeuvre: he wrapped his arms around the pit of the boy's stomach then squeezed it several times.The Lorca police officer repeated manoeuvre until the little boy expelled the piece of food that was stuck in his throat and was preventing him from breathing. Afterwards, both the mother and the child went inside the police station and were attended by other officers.The Spanish National Police's officers reportedly start learning first aid techniques as soon as they start training at the academy.
