His mother is said to have called the emergency services. Dailymail.co.uk reports that the actor was taken by ambulance to St Joseph's hospital in Burbank, where he was pronounced dead at 2.15 a.m.

Haim had a well-documented struggle with drug addiction.

While the LA coroner's office has yet to carry out a post-mortem, there was no evidence of foul play.

Haim, had flulike symptoms before he died and was getting over-the-counter and prescription medications, Sgt William Mann of the Los Angeles Police Department said.

"He could have succumbed to whatever (illness) he had or it could have been drugs. Who knows?' Mann said. "He has had a drug problem in the past."

Haim rose to fame in the 1980s when he featured in a number of films, including "Lucas", "Murphy's Romance" and the 1987 cult vampire film "The Lost Boys". He teamed up with Corey Feldman in "The Lost Boys" and it led them to be dubbed as ?The Two Coreys'.

But in the 90s, Haim slipped into obscurity after several films went straight to video without a cinematic release, and spent time in and out of rehab receiving treatment for a prescription drug problem.

Haim acknowledged his struggle with drug abuse to The Sun in 2004.

"I was working on ?Lost Boys' when I smoked my first joint. I did cocaine for about a year and a half, then it led to crack," he had said.

The actor said he went into rehabilitation and was put on prescription drugs. He took both stimulants and sedatives such as Valium.
