Chris Brown's Accuser's Ex-Roommate Says She Makes Up Death Threats

The woman who triggered Chris Brown's arrest has a history of making up stories about people threatening to kill her ... according to her former roommate.

Baylee Curran filed a restraining order in 2013 claiming her roomie, Princeton Roseborough, threatened to hire a hitman to take her out.

Baylee went on to claim Roseborough physically hurt her by pushing her head against a bedroom wall ... hard enough to call an ambulance.

Her claims were enough for a judge to issue a temporary restraining order, but when it came time for a formal hearing, she was a no-show in court so the restraining order was lifted.

Princeton, the roommate, insisted in his own legal docs that she was lying. He says Baylee was about to physically attack his girlfriend, and all he did was restrain her, and never pushed her. He submitted photos of her after the incident, which he says show no signs of injury. The photos in the legal docs are too grainy to know for sure.

Either way ... the case was dismissed.
