Colin Farrell was once arrested for attempted murder as a teenager

Colin Farrell has revealed he was once interrogated by Australian police for attempted murder.

It was as the the-then-teenage actor was visiting Sydney, with the actor admitting that he was absolutely terrified of the police who took him in for questioning.

Whilst it was a horrific ordeal for Farrell, art would later inmate life as he went to star in seasoned investigator Ray Velcoro in True Detective.

Farrell made the astonishing revelation on The Tonight Show with Jimmy Fallon, back in 2015 whilst he was promoting the gritty crime drama.

After a tense line of questioning by Jimmy Fallon and his co-star Vince Vaughn, the 46-year made a confession about how he’d been questioned during his youth.

The actor had initially been on holiday and had been partying the night before he was taken in for a crime worthy of the HBO show.

It turns out someone with an uncanny resumable to the Irish man had brutally beaten a man and set fire to his apartment in Sydney.

Things soon escalated as the young Farrell began to question whether he could have committed such as crime and struggled to remember the hazy night before.

“It was a long time ago and I was drunk. I saw a photo-fit of the guy that actually did the crime and it looked remarkably like me and for a second I - because I had had a blackout that night - I wondered, 'could I have done such a thing?'” The In Bruges star joked as he recalled the incident.

Sweating under the police interrogation, the actor had began to panic as investigators revealed key details about the attempted murder.

"They showed me a photo-fit, a pencil sketch of the guy that had attempted to murder, this other gentleman - had beat him up and left him in his own apartment, set the apartment on fire and split, thereby leaving him to burn to death - and it was me,” he confessed, then quipping: “They had bushy eyebrows, a mole on his face, spoke even in 2D with an Irish accent."

Though it was a case of mistaken identity, Aussie police were convinced Colin Farrell was, in fact, his no-good doppelganger.

It then dawned on the actor that he might not be able to make them believe otherwise, with the Oscar winner admitting on The Tonight Show that he thought he was in ‘trouble’.

"It was terrifying,” he admitted, adding that it been particularly unpleasant due to the partying he’d done.

“I was there for about six hours and then thankfully a friend of mine had kept a journal of that particular night and that particular time we were at a party the other side of town doing ecstasy..." he confessed, saying that he had been due to take his mother to the airport shortly after.

Thankfully, Farrell was let go and was able to use the unpleasant run-in with the law as inspiration for the HBO show.
