South Korean actor Lee Sun-Kyun, best known for his role in the Oscar-winning film "Parasite", was found dead Wednesday in an apparent suicide according to a police official.
The actor was discovered inside a vehicle at a park in central Seoul, Yonhap news agency reported, citing police.
Lee, 48, had been under police investigation over his alleged use of marijuana and other psychoactive drugs.
Once celebrated for his wholesome image, local news outlets reported that the actor was being dropped from television and commercial projects following the scandal.
A graduate of South Korea's prestigious Korea National University of Arts, Lee made his acting debut in 2001 in a television sitcom titled "Lovers."
He later won acclaim for his performances in a variety of roles, including a charismatic chef and a diligent architectural engineer who learns his wife cheats on him.
Globally, he is best known for his portrayal of the wealthy and shallow patriarch in director Bong Joon-ho's 2019 Oscar-winning film "Parasite."
His last film, this year's horror flick "Sleep" - in which he played a husband whose sleepwalking eventually leads to horrifying circumstances - was well-received critically and featured in the Critics' Week section at the Cannes festival.
He briefly spoke to reporters in late October before entering an Incheon police station to meet with investigators.
"I sincerely apologize for causing great disappointment to many people by being involved in such an unpleasant incident," he said at the time.
"I feel sorry for my family, which is enduring such difficult pain at this moment.
"Once again, I sincerely apologize to everyone."
South Korea has extremely tough laws on illegal drugs, with even Koreans who take drugs like marijuana legally abroad risking prosecution upon returning to their home country.
This year, President Yoon Suk Yeol called for more stringent measures to eliminate drug traffickers, saying the country was no longer "drug-free."
He is survived by wife and actress Jeon Hye-jin and two sons.
