A Thai video game addict died in front of his computer after a string of marathon all-night sessions, police said Thursday.

The body of the 24-year-old man was found slumped in his chair in his room in Samut Songkhram province southwest of Bangkok, according to authorities.

"He was addicted to games. He hardly went to bed but always played computer games from night until morning," local police officer Chaichana Boonrod told AFP by telephone.

His body will be sent for autopsy to determine the cause of death, police said.
