A Peruvian airline passenger tried to force his way into the cockpit of a domestic flight to read a manifesto over the plane's sound system, according to the state news agency Andina.
The man on an Aerocondor flight between Arequipa and Lima on Friday threatened the lives of passengers and crew if he was not allowed to speak with Peru's President Alan Garcia, the news agency said.
The passenger, identified as Wilbert Vivanco Farfan, 47, was subdued by the crew 15 minutes before the plane landed in Lima. Police found a Swiss Army knife in Vivanco's luggage when he was detained upon landing.
Airport police told The Associated Press on Saturday they were not authorized to provide more details about the incident.
