Murder charges against rapper Cassidy have been reduced in severity from first-degree to third-degree murder.

Municipal court Judge MARSHA NIEFIELD ordered the 23-year-old I'M A HUSTLA star to stand trial on the new charge, which stems from a 15 April (05) shooting in Philadelphia.

Cassidy, real name BARRY REESE, is charged with murdering 22-year-old Desmond Hawkins and wounding Daniel Irvin, 22, and Bobby Hoyle, 21 after a dispute earlier in the day.

The men allegedly came to Cassidy's Philadelphia home to "make peace", but were instead met with a barrage of gunfire as they sat in their parked car, reports.

Irvin and Hoyle were wounded while Hawkins died in hospital.

During preliminary hearings, Cassidy's case was bolstered when one of the victims admitted under oath that he initially lied to police and had not actually seen the rapper fire a weapon.

Prosecutors claim that Cassidy and his associates fired at least four guns. The team bringing charges against the star plans to appeal the new court ruling.
