CHICAGO (WGN) — Normal operations have resumed at Midway International Airport after a bag exploded on a belt while being loaded onto an outgoing Volaris flight.

Volaris is a low-cost Mexican airline. The incident happened at Gate A2 at about 12:20 p.m. Monday.

A Level 1 hazmat situation was called, but has since been cleared.

An airport source told WGN there’s nothing to suggest a sinister motive. Authorities are investigating to determine if it was some type of battery that exploded.

Bag was affected by a possible cell phone battery or battery charger. Incident was cleared by the bomb squad and no one was injured. Thanks to everyone for being vigilant and to the firefighters, officers and technicians who assisted. https://t.co/EZEnQVt5nU
