Mohamed A. Salim says the passenger compared him to the men accused of carrying out the Boston Marathon bombing 11 days earlier and threatened to kill him.

“Because I’m a Muslim, he treated me like a piece of trash,” Salim said. “I love this country. I didn’t deserve this.”

Ed Dahlberg of Clifton, who has been charged with misdemeanor assault, denied hitting Salim in a statement released by his attorney.

Muslim rights workers said Salim’s account is supported by medical records and an 11-minute, obscenity-filled video of Dahlberg’s remarks leading up to the alleged assault. Salim, a 39-year-old from Great Falls, provided The Washington Post with a copy, which his attorney described as evidence of the prejudice that others sometimes face but rarely document.
