An employee of the private contractor that runs the U.S. Immigration and Customs Enforcement detention center in Aurora, Colorado, was arrested Thursday night on suspicion of attempted second-degree murder after police said he fired a single shot at demonstrators blocking the facility, wounding a woman in the lower body.

Brandon Booth, 42, was detained less than two blocks from the shooting scene on the 3100 block of North Nome Street, and officers recovered a pistol from his vehicle, the Aurora Police Department said.

Booth is an employee of GEO Group, the private prison company operating the Aurora ICE Processing Center.

According to the police department's news release, Booth was waiting in his vehicle alongside other employees who could not access the facility for their shifts because of the protest.

Police said two women broke away from the demonstration, engaged in a verbal confrontation, and photographed the employees' vehicles before walking away.

Booth then retrieved his personal firearm and fired one shot in their direction, striking one of the women, police alleged. He drove off before officers stopped him a short distance away.

The wounded woman was taken to a hospital with injuries that Aurora police described as not life-threatening. She has not been officially identified, though Colorado Public Radio reported her name was listed in court and in a GoFundMe appeal as Emma Landis.

Booth was booked on suspicion of attempted second-degree murder, first-degree assault, attempted first-degree assault, felony menacing, and unlawful carrying of a concealed weapon.

Filing decisions rest with the 17th Judicial District Attorney's Office.

He appeared Friday afternoon in Adams County, where Magistrate Kyle Martelon set bond at $500,000, calling Booth "a grave risk to our community."

A defense attorney told the court that Booth had worked at the GEO facility for 2 1/2 years and previously worked in state juvenile corrections.

In a statement, GEO Group said it was aware "an off-duty Aurora ICE Processing Center employee was involved in a shooting incident" and placed him on unpaid administrative leave.

Aurora Police Chief Todd Chamberlain called the case "a tragedy on all fronts," saying his department would investigate with "transparency and integrity" and adding, "Constitutional rights are a pivotal part of a just society; violence is not."

The shooting comes as the Aurora facility remains under state scrutiny over a tuberculosis case and follows two fatal ICE-involved shootings this month in Houston and Biddeford, Maine.

The Department of Homeland Security paused most ICE traffic stops after those killings; President Donald Trump reversed the pause Wednesday.
