Incheon International Airport has filed a lawsuit against actor Byun Woo Seok's controversial security team.

On July 25, the Incheon International Airport officially filed a lawsuit against the security company that worked with Byun Woo Seok due to their actions on the 12th. The cited complaints include blocking the airport entry gate and checking the passenger tickets thus abusing their authority. 

Police interviewed a security guard as a witness for the investigation yesterday, and airport security personnel were questioned last week as well. 

As previously reported, Byun Woo Seok's private security team issued an apology after flashing lights at fans at the Incheon International Airport as well as allegedly checking the passports and boarding passes of citizens during the actor's departure. Though Byun Woo Seok's label Varo Entertainment also issued an official apology and dropped the security team, the backlash and criticism did not die down.

Stay tuned for updates.
