Two 15-year-old boys are accused of attacking a man on a MAX train in Portland last month, breaking his jaw and knocking out a tooth, after he asked them to turn their music down.

Robert Valentino told police he was on the MAX train Dec. 27 with his wife and 10-year-old daughter to see another relative when nine teens boarded playing loud music coming from a speaker, according to a probable cause affidavit. Valentino said he told them to turn it down, one of them did and then turned the volume up louder and pushed the device in Valentino’s face.

Valentino threatened to take the speaker away and was repeatedly punched in the head and body by several of the teens as the train was near Northeast 60th Avenue, the affidavit said. Someone called 911, police arrived and used surveillance footage to identify Marquavious Ware and Jerimiah Hannon as Valentino’s suspected attackers.

According to the court documents, Ware told a detective that he and others punched Valentino in the face several times. Both teens are accused of second- , third- and fourth-degree assault and interfering with public transportation.
