A Spokane man accused of assaulting his infant daughter pleaded not guilty to the charge Tuesday.

Daniel S. O'Brien, 23, was arrested Feb. 10 after he and his girlfriend, Jordan Calvert, brought their 2-month-old daughter, Tristan, to a Spokane hospital with bruises and fractured bones, including a broken rib and fractured skull.

O'Brien reportedly admitted to causing the girl's injuries and said he had mental problems that caused him to blackout when angry. He told police he'd sought mental health services but couldn't pay because he didn't have insurance, according to court documents.

O'Brien is in Spokane County Jail on $50,000 bail for one count first-degree assault of a child. His next court date is in April.
