As a condition of his release, Sheriff Boen may not “engage in any sheriff-related activities,” Mr. Wood said, but he remains in the position.

In a statement, Mr. Wood said that his client had no comment, but added that “the 3 inmates that made the allegations against Sheriff Boen have serious credibility issues.”

Attempts to reach Sheriff Boen at his home on Tuesday were unsuccessful.

According to officials, the indictment contends that Sheriff Boen used “unreasonable force to punish pretrial detainees on three separate occasions.”

Sheriff Boen, who was first elected to his position in 2011, is accused of having assaulted one detainee in 2017 and two more in 2018.

On Sept. 14, 2017, Sheriff Boen is said to have punched a person he was transporting “multiple times in the head and body” while the person was “handcuffed and shackled in the back of a patrol vehicle” and not resisting, the indictment said.
