Investigators have revealed how the Hells Angels were inspired by the Mafia - with new joiners required to commit murder in order to be accepted into the notorious biker gang.
The startling admission was laid bare in A&E's Secrets of the Hells Angels docuseries which has taken a deep dive into the history of the 'outlaw' group.
In an upcoming episode, seen exclusively by DailyMail.com, retired police detective Tom Doyle did not hold back in divulging the blood-thirsty entry requirements.
The former cop, from Eastlake Police Department, Ohio, explained how The Godfather - a crime novel about fictional Mafia family headed by headed by Vito Corleone - had formed the basis of the biker gang's code of conduct.

Explaining how the law of Hells Angels came about, Doyle said: 'While in jail, someone obtains a copy of The Godfather and it's read and passed around.
'To become a "made" member of the Mafia, you have to commit a murder. [The Hells Angels] sit there and look around the cell block and they realize "we've already done that."
'Then they realized if you have an organization where everyone is bonded by murder the person who commits the murder is not going to turn on the club - that ensures silence and that ensures loyalty.'

Kerrie Droban, author and attorney, said of the biker group: 'They fell in love with the whole law of the Mafia and they were able to take a lot of those philosophies and ideologies...
'If you're willing to do this, then you are willing to be a brother for life.'
And Doyle conceded that this is soon how the group started operating, as he added: 'It was a closely-guarded secret.
'New members are required to roll your bones - required to kill. In The Godfather, they "make their bones." Bikers "roll their bones."'
Links between the Hells Angels and the Mafia have been the subject of much scrutiny over the years, with one report back in 1986 revealing that the FBI was investigating possible ties between the two notorious groups.
At the time, an FBI organized crime squad agent, Jim Ring, suggested that the Hells Angels would step in to 'nibble away' at mob boss ventures whenever the Mafia found itself 'out of action'.
'Whenever a certain La Cosa Nostra group is taken out of action, other groups will try to step in and nibble away at that business,' he said, according to UPI, adding: 'We know in certain parts of the country it has been firmly established through court evidence that the Hell's Angels do business with the (Mafia).
'We think there is reason to monitor the situation in Boston to see what contact they do have and see if it fits into the furthering of the criminal enterprise.'
Doyle's fascinating new revelation about the Hells Angels' ties to the Mafia comes after Jay Dobyns, an undercover cop who infiltrated the biker gang for two years, spoke exclusively with DailyMail.com about the dark underbelly of the biker group.
The now 62-year-old was embedded within the group in Arizona between 2001 and 2003 after joining the Bureau of Alcohol, Tobacco and Firearms (ATF).
He described the operation as a 'life and death experience' during which time he saw that 'the Hells Angels were willing to kill their own' and 'just how violent they can be.'
Jay also candidly divulged how he caused his family an 'immense amount of battle damage' during his assignment and was left facing death threats after his cover was finally exposed.

It was a brutal and bloody murder that prompted Jay's infiltration of the notorious gang, with the former undercover cop revealing how ATF had ramped up its investigation of the Hells Angels after two 'key events that were the cornerstones of the investigation.'
The first was the murder of Cynthia Garcia who Jay said was 'beaten to near death in the Hells Angels clubhouse in Massa, Arizona.'
He continued: 'And, when she wasn't dead yet, they stuffed her in the trunk of a car and they drove her to the desert near Apache Leap in Arizona and they cut her throat. They tried to cut her head off.'
The former cop said that the other flashpoint had been the public riot at a casino in Laughlin, Nevada, which saw the Hells Angels in a bloody clash with rival group the Mongols.
Jay also shared his own experiences with the biker gang's initiation procedures, describing it as a 'very slow process'.
'They are very paranoid and they are paranoid for legitimate, good reasons,' he said. 'Their paranoia keeps them out of jail, their paranoia keeps them out of prison, their paranoia keeps them from being infiltrated because when you arrive on scene, they view you as one of two things.
'They view you first as a threat - as someone who is looking to hurt them. Then they also look at you as a victim - as someone who could eventually be taken advantage of.
'You slowly start climbing the ladder and as you spend time around the suspects you begin to build trust and then that trust leads towards loyalty and then the loyalty in some cases leads to love.
'But it's a very slow, tedious process - it's like any relationship. Those things don't happen instantly they happen over time.'
The latest episode of A&E's Secrets of the Hells Angels will air on April 21
