After less than 10 minutes in the air, an Alaska Airlines flight was forced to make an emergency landing on Monday when a napping baggage handler woke up in the plane's cargo hold and began banging and screaming.

In an official statement, the airline confirmed that the L.A.-bound flight returned to Seattle when the pilot "reported hearing banging from beneath the aircraft" immediately after takeoff. According to KIRO-TV reporter Alison Grande, passengers also heard screaming.

Upon landing, an airport employee walked out of the plane's pressurized and temperature-controlled front cargo hold, reportedly telling authorities "he had fallen asleep." The man was then taken to a local hospital as a precaution and released shortly afterward.

Alaska Airlines says they are "actively investigating" the incident.
