A 14-year-old boy fatally shot his entire family after getting influenced by the online game "PlayerUnknown's Battlegrounds" also known as "PUBG," police said Friday. The shocking incident took place in the capital of Pakistan's Punjab province.

Nahid Mubarak, a 45-year-old health worker, was found dead along with her 22-year-old son Taimur and two daughters aged 17 and 11 in Lahore's Kahna area, India Today reported. The teenage boy, who has not been identified, was the only one unhurt. Authorities said in a statement that the teenager shot and killed four members of his family.

“The PUBG (PlayerUnknown's Battlegrounds) addict boy confessed to have killed her mother and siblings under the influence of the game. He has developed some psychological issues because of spending long hours of the day playing the online game,” the statement said, according to NDTV.

Police said Nahid was a divorcee and often used to scold her son for not paying attention to his studies and spending most of his time playing PUBG.

"On the day of the incident, Nahid scolded the boy over the matter. Later, the boy took out his mother's pistol from a cupboard and shot her and his three other siblings dead in their sleep," police said. "Next morning, the boy raised an alarm and the neighbors called the police. The boy that time told police that he was on the upper storey of the house and did not know how his family was killed."

Authorities said that the gun was a licensed pistol acquired by Nahid for her family's protection. The boy allegedly threw the gun in a drain after killing his family. The weapon is yet to be recovered.

A similar incident took place last year when a 13-year-old boy in India's Uttarakhand state allegedly killed his same-aged neighbor after the two had an argument over the video game PUBG. The teenager attacked the victim with a glass-like sharp object resulting in the neighbor sustaining fatal injuries. The victim was rushed to a hospital where he succumbed to his injuries.

The World Health Organisation (WHO) has officially included gaming disorder as a disease in the International Classification of Diseases.
