An 18-year-old high school drop-out from Korea is suspected to have joined Daesh after tweeting about his interest in joining the terrorist organization using the account "Sunni Mujahideen," reports Agence France Presse.
Police said Kim posted a series of messages on his Twitter account in October last year, asking for help in approaching Daesh.
"How to join [Daesh]? Does anyone know? I want to join [Daesh]," he tweeted.
"Many materials suggest that he was greatly interested in [Daesh], but we cannot confirm whether he has joined them," Chung Jae-Il, a senior Seoul police officer told journalists.
The male teenager went missing in Turkey earlier this month, and it is suspected he crossed into Syria, reports the Agence France Presse. He was last seen leaving a hotel in the southern city of Kilis.
According to Agence France Presse, a South Korean foreign ministry official said Tuesday that CCTV footage obtained by Turkish police showed Kim taking an unlicensed taxi, together with an unidentified man, outside a mosque near his hotel.
