Notorious bikie Troy Mercanti is a free man after his release from prison last week.

The West Australian understands Mercanti was released on Thursday after serving almost seven years behind bars for violence inflicted on his former wife Tammy Kingdon.

The former Coffin Cheater, turned Fink, was rarely out of the news in the years leading up to his sentencing on March 13, 2013 by Judge Simon Stone who called him a deceitful coward for his attacks on Ms Kingdon.

Mercanti, now 51, was already incarcerated at the time, having breached strict conditions of his home detention bail after testing positive for methamphetamine before the trial.

Judge Stone sentenced the bikie to six years and 10 months jail but made him eligible for parole and backdated the sentence by a year.

The judge warned those responsible for Ms Kingdon’s welfare, which had involved police protection, that Mercanti would pose a threat to her in future.

During the District Court trial, Ms Kingdon gave video-link evidence from a secret location over six days.

She told how Mercanti punched, kicked and “king-hit” her, resulting in a fractured cheekbone, knocked-out tooth and fractured ribs.

In two incidents Ms Kingdon had pleaded for help in the street while naked.

Judge Stone said she was a credible witness who suffered at the hands of a “cruel” and “remorseless” liar.

“You repeatedly falsely accused Ms Kingdon through your counsel ... of being a liar, an actress, a drama queen, an exhibitionist, a fabricator of evidence, a prostitute and vengeful whilst you were aware that her allegations were true,” Judge Stone said.

“Your conduct was deceitful. You beat her without mercy. Mr Mercanti, you are a coward.”

The judge said it was only the Finks bikie’s realisation midway through his trial that he would inevitably be found guilty that prompted him to finally admit assaulting the mother of his two sons four times during their 16-year relationship.

His mother, Sybil Yvonne Mercanti, had forced back tears to tell the court she had seen him punch Ms Kingdon at a family Christmas event in 2006.

The blow had knocked out Ms Kingdon’s tooth and left the family traumatised.

Mrs Mercanti said she loved her imperfect son.

In 2010, Mercanti’s switch to the Finks after being turfed out of the Coffin Cheaters sparked a feud that erupted into a bloody shootout at the Kwinana Motorplex after members unexpectedly turned up to the same event.

In February 2008, Mercanti needed hospital treatment after being bashed by 12 to 15 of his former Coffin Cheater comrades.

A few months earlier, in May 2007, Mercanti broke the jaw of a 26-year-old man at the Geisha Bar in Northbridge.

In another infamous flashpoint, Mercanti was stabbed and slashed by Scorpion Boys gang member Nabil Dabag in a fight at Northbridge’s Metro City nightclub in January 2005.

Dabag was shot five times in the showdown.

A former associate of Mercanti, Fabian Quaid, was also released from prison recently.

The 41-year-old, who now uses his birth name Fabian Irani, was released from Wooroloo Prison Farm on November 20 after serving 10 years and six months behind bars for his role in an ecstasy conspiracy worth up to $24 million.
