cellblock
n.— «Pulled off the streets, stripped of guns and badges, kept inside four walls and away—as much as possible—from the public, officers who are put on desk duty because their conduct is under investigation find themselves far from the enforcement activities they signed up to do. “We like to call it the ‘cellblock’ because it is like you are in prison,” said an officer who spent more than 18 months watching surveillance video while authorities investigated an accusation that he had struck a suspect.» —“To the Police Dept., It’s Desk Duty. To Some Officers, It’s More Like a Cellblock.” by Christine Hauser New York Times Nov. 29, 2008. (source: Double-Tongued Dictionary)
