Actor and comedian Tracy Morgan is in a critical condition following a six-vehicle crash in the early hours of Saturday morning that killed one person, police have said.

The former Saturday Night Live cast member and 30 Rock star was a passenger in a limo bus that overturned during the pile-up on the New Jersey Turnpike at about 1am, CNN have reported.

Authorities said one person has died and four others were injured in the accident, which also involved two tractor-trailers and an SUV.

The bus Morgan was travelling on was carrying seven people, one of whom was killed, state police said. He was transported to Robert Wood Johnson University Hospital in New Brunswick and is being treated in intensive care.

Peter Haigney, a spokesperson for the hospital, said four patients are being treated there. Three are in a critical condition while one is in a “fair condition”, according to the network. Morgan was named as one of the three in a critical conditon.

The 45-year-old joined Saturday Night Live in 1996 and was on the sketch-comedy programme for seven years before leaving to star in The Tracy Morgan Show in 2003.

That show lasted just one season. In 2006, Morgan found a long-running role in NBC's hit show 30 Rock, which was created by Tina Fey.
