Shots were fired in the vicinity of Terminal 2 of Mexico City's international airport on Friday morning with at least two people injured and one suspect arrested, according to the capital's police chief.
Chief Omar Garcia Harfuch said in a post on Twitter that the two injured were "out of danger," adding that the detained suspect had also been shot and injured.
The incident was likely sparked by a robbery attempt in which a bodyguard fired shots in order to repel an alleged robber on a motorbike, according to officials. It was not immediately clear if the suspect or others also fired weapons.
Images published by outlet Telediario showed a black SUV with bullet holes in the windshield and a crumpled motorcycle in front of it, just a short distance from the terminal's normally bustling traffic circle where passengers arrive at and leave the airport.
National Guard police said the perpetrator of the attempted robbery had followed the SUV from a nearby subway station.
Operations at the airport, Mexico's biggest, have not been affected, according to the airport's media office.
