A detective constable has appeared in court to deny perverting the course of justice.
DC Lucy Page of Leicestershire Police allegedly provided incorrect information to a senior police officer between October 16 and October 25 last year.
A court heard the information – and an alleged falsification of a custody record sheet – intended to extend the period of time a suspect was in custody.
On Thursday, the 30-year-old spoke only to confirm her name and to deny the charge in an eight-minute hearing at Leicester Crown Court.
Judge Marcus Tregilgas-Davey granted Page unconditional bail until her four-day trial scheduled for December 17.
A spokeswoman for Leicestershire Police said Page, of Old Station Road, Syston, Leicester, had been suspended from the force.
