Ezra Wallace, a 29-year-old man from Denver, says he was just "horse playing" around when he tied with tape a teenage girl seated beside him in a Southwest Airlines San Diego-to-Denver flight last August 1.

Wallace admitted that he was drunk when he bound the teenager. He added that he "never harmed anybody or had any bad intentions." He was also attempting to do the same with the teenager's younger sister, according to witnesses.

Federal Judge Kristen Mix said there is enough evidence to proceed with two counts of assault charges against Wallace. Mix set bail at $5,000 including several conditions wherein Wallace was not allowed to drink alcohol and should undergo urinalysis and breathalyzer.

During the incident, Wallace reportedly tried to take a photo of the older sister. The teenager hesitated and covered her face with her hands.

The younger sister said that Wallace got tape from his backpack and used it to tie her sister's hands together, after which, he attempted to tie the younger sister's hands too.

The older sister tore off the tape with her teeth. A flight attendant saw the incident and moved the sisters to different seats near their brother.

FBI agents arrested Wallace at the Denver airport. He was reported to have consumed vodka during the flight.
