A judge has ruled to withhold from Suge Knight’s lawyers the identities of witnesses in the murder case against the Death Row Records co-founder, according to Billboard.

Suge’s lawyers originally sought the information and addresses of several potential witnesses, including three confidential informants, in an effort to independently interview them to prepare a defense for Knight. But prosecutors objected, pointing to Knight’s history of violence and intimidation.

On Friday, after meeting privately with a prosector and a detective, Los Angeles County Superior Court Judge Ronald Coen ruled in their favor, claiming they’d shown sufficient reason to request the protection of the witnesses’ identities.

Last year, Knight was charged with murder and attempted murder after being the driver in a fatal hit-and-run on the set of “Straight Outta Compton.” He has pleaded not guilty.
