A US man, on board a Delta Carriers departure from Los Angeles to Seattle, was kept on Saturday for purportedly opening a leave entryway and causing the plane's crisis slide to be enacted before departure.

The Los Angeles Air terminal Police said around 10am EST., a unidentified traveler, wearing a striped red and naval force blue sweater with dark jeans, hurried to the front of the plane while the plane was driving away from the entryway and asked the airline steward, "what do I do now?", detailed the New York Post.

As per the report, travelers told FOX 11 that the airline steward demanded that the man plunk down, however he ran from the airline steward and went to the plane's crisis leave entryways, turned the hook, opened the entryway, and slid down the conveyed crisis slide.

Compelling the plane to stop, the man hopped onto the rear of a stuff truck, where baggage laborers held him down until the air terminal police arrived, the report cited the travelers as saying.

"He is being taken to a neighborhood emergency clinic for a psychological assessment," said a security staff.

"Air terminal Police answered and kept the traveler for additional examination. Because of the conditions, FBI was informed," the air terminal police told Fox News Advanced.

The carrier told Fox News Advanced, "Delta flight 1714 working from Los Angeles to Seattle got back to the entryway because of a boisterous traveler. The airplane was holding to taxi for departure when the traveler left the airplane and was at first confined by Delta staff in front of being captured by nearby policing."

"Clients are being re-obliged on another airplane, and we apologize for the bother and postpone in their itinerary items," it added.
