The tragic death of 27-year-old Star Trek actor Anton Yelchin has been confirmed as an "accident caused by blunt traumatic asphyxia", according to LA Police.

Yelchin, best known for playing Chekov in the recent sci-fi movies, was found dead early on Sunday morning at his home in Studio City, Los Angeles. His car had rolled backwards on the steep driveway, pinning him against a brick postbox and security fence. 

The car, a 2015 Jeep Cherokee, was one of 1.1 million Fiat Chrysler vehicles worldwide subject to a recall because of a gear shift problem that has confused drivers.

Fiat Chrysler has said it is investigating the accident, telling media outlets the company would conduct "a “thorough investigation" of the incident, but adding that "it is premature to speculate on its cause at this time."

Yelchin had been on his way to meet friends for a rehearsal when the accident occured.

"When he didn't show up, his friends went to his house, where they found him deceased by his car," said Los Angeles Police Department spokesperson Jenny Hauser. "It appeared he had momentarily exited his car, leaving it in the driveway."

Following his tragic death, Yelchin also becomes another member of the so-called '27 Club' which refers to the age at which a number of well known stars lost their lives including Amy Winehouse, Kurt Cobain and Jimi Hendrix.

He appeared on The Late Late Show back in 2011 alongside Christopher Mintz-Plasse (Superbad's McLovin) who was his co-star from the movie, Fright Night, which also starred Colin Farrell. The pair had arrived on the talk show fresh from seeing the Republic of Ireland play Slovakia at the Aviva Stadium, complete with Ireland jerseys.

Anton won over the room by diplomatically telling Tubs that the nil-all result was due to "A little bit of unfair reffing". He also spoke about finding himself part of the Star Trek universe and admitted that since he started playing Chekov in he had to get used to attention from die hard Trekkies.

"There's always a couple outside of my house, hanging out. Armed to the teeth - dressed as me", he joked.

Yelchin began his acting career appearing in shows such as ER, Curb Your Enthusiasm, and Law & Order: Criminal Intent. In 2006, he received critical acclaim for his performance in crime drama Alpha Dog and starred as the title character in 2007's Charlie Bartlett and also had roles in Terminator Salvation and Like Crazy. 

He made his Star Trek debut in the franchise's 2009 film, where he played Pavel Chekhov. He reprised the role in 2013's Star Trek Into Darkness and again in the upcoming Star Trek Beyond.
