Authorities said Tuesday that a man who attacked rapper Tory Lanez in a California prison is an inmate serving a life sentence for second-degree murder who was previously convicted for an in-prison assault with a deadly weapon.

Rapper Tory Lanez is in hospital after being stabbed 14 times by a fellow prison inmate. He is serving a 10-year sentence for shooting his ex, hip-hop megastar Megan Thee Stallion, in the feet during an argument in 2020.

Lanez was sentenced to 10 years at a state prison for shooting Texas rapper Megan Thee Stallion in 2020. Despite Lanez being behind bars, him and Megan— real name Megan Pete— are still battling each other in court.
