18 year-old Akira Smith is in the Missoula County Jail on felony aggravated assault charges for allegedly attacking his sister, cutting off her breathing with a headlock.

Missoula Police Public Information Officer Travis Welsh said the call came in on Saturday.

"At about 2:09 a.m. officers were called to an address in the 1500 block of North Russell Street for what was described as a physical disturbance between a male and a female," Welsh said. "The officers arrived and made contact with a male and learned that he had been in an altercation with his sister, and admitted that he had but her in a headlock."

Welsh said the man's sister described the attack as a felony.

"The sister repeated the same story, except to say that the headlock actually limited her ability to breathe normally, so Mr. Smith was arrested and charged with aggravated assault. He was placed in jail on $50,000 bond."

Smith appeared in Missoula Justice Court on Monday afternoon.
