An Idaho Springs police officer was arrested this week on suspicion of assault after a May 30 incident that left a man hospitalized.

Nicholas Hanning, who has been on administrative leave from the Idaho Springs Police Department, turned himself in on Wednesday after a warrant for his arrest was issued. He is accused of third-degree assault of an at-risk adult, Class 6 felony, according to a news release from the 5th Judicial District Attorney’s Office.

Bond was set at $2,000 cash or surety, which Hanning posted. Formal charges are expected by 4 p.m. on July 12, and the officer’s next appearance is scheduled for 9 a.m. July 13.

ISPD will decide in the next week whether to continue Hanning’s employment. He’s been with ISPD for three years and doesn’t have any previous complaints related to use of force, police Chief Nate Buseck said.

Buseck said another officer, Ellie Summers, has been disciplined internally after investigation into the incident. Summers, who has been with ISPD for two years, also has no previous complaints related to use of force.

On May 30, Hanning and Summers responded to a woman claiming she’d been assaulted by a man. The officers contacted the man, who is in his 70s, in the 3200 block of Riverside Drive. He answered the door holding a sword-like weapon with what appeared to be metal teeth along both edges, prosecutors said.

A fight between Hanning and the man ensued, during which Hanning deployed his Taser. The resident was injured and taken to a local hospital.
