Douglas County District Judge Peter Bataillon ordered Officer Dyea L. Rowland to cooperate with prosecutors in the evidence-tampering case against fired Officer James Kinsella.
Prosecutors sought the order, fearing Rowland would refuse to testify based on her right against self-incrimination.
The case stems from the March 21 arrest of three brothers that was secretly recorded by a neighbor. The recording shows a man being punched by an officer while he was restrained.
Prosecutors say Kinsella illegally confiscated a cellphone memory card from the man’s brother, who also videotaped the arrest, and threw the card away.
