The summary report stated that on the evening of April 29, an “unidentified man” dropped off a package at the diplomat’s building before rushing off.
“The package had contained a blackmail letter, two small bottles allegedly containing alcohol, and three pictures of a parking garage used by the senior official, which was marked with an X in chalk,” the report said.
The report went on to say the letter sent to the North Korean official allegedly demanded that he “cooperate with certain organization through a secret contact” and that failing to do so would threaten his “personal security.”
The diplomat reported the incident to police and had several subsequent meetings with them. However, North Korea alleged during the June meeting that, to-date, they had not received any further information regarding the incident.
