Boise police Lt. Kent Lipple told The Idaho Statesman that Russell Miller, 68, was upset with a 15-year-old passenger who would not turn off his phone despite directions from the crew of a Southwest Airlines flight coming in from Las Vegas Tuesday night.
"He thought he had to take action," said Lipple.
He said Miller punched the teenager, who was flying alone, in the arm, leaving a mark, but the teen did not require medical attention.
Miller was booked into the Ada County Jail on a misdemeanor battery charge.
"The suspect decided to act on his own accord and he is going to spend some time in jail," Lipple said.
