Fallen rap mogul Marion 'Suge' Knight is reportedly receiving treatment for a potentially-fatal blood clot after collapsing outside a court in Los Angeles on Tuesday (03Feb15).

The Death Row Records founder pleaded not guilty to charges including murder and attempted murder stemming from a car accident in L.A. last week (ends01Feb15) which killed his friend Terry Carter, and left actor Cle 'Bone' Sloan injured.

After the hearing on Tuesday, Knight collapsed outside the court house and was taken to a local hospital.

Previous reports suggested he had suffered a panic attack, but it has now emerged Knight experienced severe chest pains and is now receiving treatment for a potentially life-threatening blood clot.

The 49 year old has also been moved to another hospital, the Long Beach Memorial medical centre in California.

Editors at Tmz.com report the clot is linked to injuries he received in a shooting at a party in L.A. hosted by singer Chris Brown in August (14). Knight suffered a number of bullet wounds and underwent surgery to treat his injuries.
