Several passengers, including a Hurricane Katrina evacuee, grabbed a violent man aboard a Frontier Airlines flight Tuesday and subdued him, authorities said.
When the plane landed, police found the plane smeared with blood from front to back and Jason Tervort, 26, duct-taped and lying face down in the center aisle.
"They worked him over pretty good," said Denver Police Detective Virginia Lopez. "The passengers did what they had to do."
Flight 147, which had left Houston Tuesday evening, was carrying a number of Hurricane Katrina evacuees, said Monique Kelso, an FBI spokeswoman.
Matthew Meador, 27, a construction worker from Lakewood who was on the plane, said Tervort was acting strangely from almost the moment the plane took off.
According to an FBI arrest affidavit, Tervort got out of his seat shortly after takeoff and began walking "very aggressively" toward the front of the plane. Tervort is accused of pushing and slapping a flight attendant, who called for help.
