A couple who allege an Uber driver tried four times to run them down in April while threatening to kill them sued the company and the driver Monday.

John Christopher Burget and fiancee Kristin Currey brought the lawsuit in Los Angeles Superior Court against Uber Technologies Inc. and driver Destiny Riddle. The suit alleges negligence, assault, battery, intentional infliction of emotional distress and false imprisonment. Burget is seeking $4.95 million in damages and Currey is asking for $750,000.

Uber hired and retained Riddle despite her "record of violent and confrontational behavior," the suit states.

Neither the plaintiffs' attorney, Mark Mazda, nor an Uber representative could be immediately reached.

The suit does not state where Riddle picked up the pair on April 22. During the ride, Currey complained to Riddle about the loud volume of the music she was playing and the offensive lyrics, but the request only caused her to become "extremely confrontational and violent," the suit states.

"Riddle refused to turn the music down or off," the suit states. "So, Burget and Currey asked Riddle to let them out of the car. Riddle refused." Riddle only permitted the plaintiffs to leave the car after they called 911, the suit states.

"However, after they were out of the car, Riddle attempted to run them over four times," the suit states. "Riddle expressly stated to plaintiffs while she was doing this that she was going to kill them."

Riddle tried three times to run the two over while driving in reverse at high speed, then turned around and aimed at them again, the suit alleges.

"The only reason Riddle stopped attempting to run them over was because the police were arriving at the scene," the suit states. "Riddle fled the scene in her Uber car and was eventually arrested by police."

Burget, who previously had knee implant surgery in one leg and a hamstring injury in the other leg, hurt himself while jumping out of the way of Riddle's car, the suit states.

Burget has had further surgery on the leg with the implant and he may lose that limb from the knee down, the suit states. He tore his hamstring in the other leg and has had flashbacks about the confrontation with Riddle, the suit states.

Currey also was injured while leaping out of the way of Riddle's car and both she and Burget suffered emotional distress, according to the complaint.

"Currey feared and still fears that Riddle would or will show up at her house and harm her, Burget, and/or Currey's children," the suit states.

The suit further states that Riddle swung an aluminum softball bat and chased for two miles in her car a process server who tried to serve her with papers the plaintiffs filed in support of their successful bid for a temporary restraining order against the Uber driver.

"That process server fled for his life," the suit states.
