The actress, who is the daughter of veteran actress Kyun Mi-ri, said she lost her phone in the morning of Oct. 17 in a crowded club in Gangnam, Seoul. Lee texted herself using another number, offering money in return for her smartphone.

One of the gang, surnamed Bae, reportedly found out that she was a celebrity and called Lee at least five times to demand 20 million won ($17,500) in return.

With undercover police, Lee met them with her manager at a cafe in Seoul where the group was caught, according to the agency.

“Bae threatened to sell information from her smartphone to newspapers or reveal them online,” Sidus HQ said in a press release.

“They illegally accessed her personal information and blackmailed her to demand money using pay phones in different locations.”

Lee has been active on TV dramas recently, making her appearance on “Scholar Who Walks the Night” and “Pinocchio.”
