FORT BRAGG, N.C. — Army prosecutors offered the first details of a rare criminal case against a general, alleging in a military hearing Monday that he committed sex-related crimes involving four female officers and a civilian.

A hearing on evidence in the case against Brigadier General Jeffrey Sinclair began Monday at Fort Bragg, home to the 82d Airborne Division. Officials said the Article 32 hearing, similar to a grand jury proceeding in civilian court, was expected to last at least two days.
