• A Delta passenger was arrested after he opened the emergency plane door right before takeoff.

• He slid down the emergency slide and later hopped onto a luggage cart.

• The man was taken to a local hospital for a mental evaluation, an airport police officer told Fox News.

A man on a Delta flight was arrested at the Los Angeles International Airport after he opened the plane door, activated the emergency slide, and slid down it minutes before his flight was scheduled to take off.

Delta Flight 1714 from Los Angeles to Seattle on Saturday was delayed due to an "unruly passenger" who exited the airplane while the "aircraft was holding to taxi for takeoff," Delta Air Lines said in a statement seen by CBS News.

Fox News reported that the unnamed man, wearing a striped red and navy blue sweater with black pants, ran to the front of the aircraft and asked the flight crew: "What do I do now?"
