Police said Friday they have arrested a man suspected of sending letters to local media, threatening to explode the plane the widow of former South Korean President Kim Dae-jung planned to take on her visit to North Korea.
  

The Seoul Metropolitan Police Agency said they have arrested a suspect who wrote a one-page letter threatening to blow up the plane in either the departure or the return of Lee Hee-ho's trip to the North.
  

Lee returned home on Aug. 8, after a four-day trip to promote reconciliation on the divided peninsula.
  

Her trip was in the spotlight on hopes it could ease tension on the Korean Peninsula, sparked by the North's nuclear and missile tests, as Lee is also a symbolic figure for inter-Korean reconciliation due to her late husband's accomplishments.
  

Kim Dae-jung, who died in 2009, was the architect of the "sunshine" policy that actively pushed for cross-border exchanges and reconciliation. He held the first inter-Korean summit with then North Korean leader Kim Jong-il in 2000. At that time, Lee accompanied her husband to Pyongyang. (Yonhap)
