Mathew Perry

The LA Times and TMZ, which first reported the Friends actor had died, said the star was found unresponsive in a hot tub at his house on Saturday.

Perry's post-mortem examination was inconclusive, while officials await the results of toxicology tests.

There were no obvious signs of trauma, an LA Police spokesperson confirmed to CBS News, the BBC's US partner.

The LA County Medical Examiner's office updated their file on Sunday to say the case had been deferred.

This usually means that the post-mortem is complete but more detail is needed.

The actor was found dead at his home in Los Angeles, law enforcement sources told US media.

Friends, which followed the fortunes of six young friends living in New York City, aired from 1994 until 2004.

Its final episode was watched by 52.5 million in the US, making it the most watched TV episode of the 2000s.
