Jeff Conaway, best known for his roles in the movie "Grease" and the 1970s TV series "Taxi", died on Friday at the aged of 60, his management company said.

Conaway, who had a history of addictions to drug, alcohol and prescription painkillers, was hospitalized earlier this month after being found unconscious in his Los Angeles area home.

He was suffering from pneumonia and sepsis, and had been placed in a medically-induced coma.
