Dana Martin, serving two life sentences in a New Mexico prison for the killing of a 15-year-old girl, told police he had hatched the scheme after Bieber never returned messages he sent to the 18-year-old "Beauty and a Beat" singer.
Police recounted in an affidavit filed in a New Mexico court that Martin, who has a tattoo of Bieber on his leg, told them the perceived slight was part of what led him to dream up the alleged murder plot.
"In the end, what Mr. Martin stated he was seeking was a measure of notoriety so that there would be people outside of prison who would know who he (Mr. Martin) was," police wrote in the affidavit.
Bieber was not the only target in the alleged conspiracy — police allege two men Martin hired were also told to kill Bieber's bodyguard and two people unconnected to the star — but he was the main one, investigators allege.
The men Martin allegedly had carrying out his plot were to use pruning shears to cut off the testicles of the first two victims in Vermont and kill them, then travel to New York, kill the bodyguard and abduct and kill Bieber, Martin told police.
There are no details in the affidavit of how the men, a recently released ex-con and his nephew, were to carry out the murder of one of the biggest stars in the world. But a celebrity security expert suggested Bieber would likely have more than one layer of protection.
"Somebody of his stature will never ever be travelling with just one bodyguard," said Adrianne Fekete-Romanick, director and owner of Star Quality Enterprises.
"People that do executive protection for celebrities or people with celebrity status are always on, basically, alert."
It's not known how much detail the members of the alleged plot knew about Bieber's security detail.
But Martin said he drew Mark Staake, 41, into his plot when they met in prison this year by telling Staake that he had access to a lot of money, had a multi-million-dollar family farm in Vermont that could serve as a hide-out and had connections in a Chinese gang in New York.
Staake brought his 23-year-old nephew, Tanner D. Ruane — his "right-hand man" — into the scheme, Martin told investigators.
Staake was released on probation at the end of October and started to track Bieber's whereabouts, Martin said. The murder was to take place in New York at the end of November, according to the affidavit, which was when Bieber was in the city to give a concert.
The uncle and nephew team arrived in Vermont on Nov. 19, but on the highway they realized they were headed to the Canadian border, according to the affidavit. They missed the last exit before the border and turned around to join the cars entering the Highgate Springs, Vt., point of entry, police said.
The U.S. border agent found Staake had an outstanding probation violation warrant from New Mexico and he was arrested.
Martin and Ruane spoke on the phone later that day, and when Ruane told Martin that Staake had been arrested, Martin called off the plot. In the phone call, which was recorded by authorities, Ruane expressed disappointment at Martin's decision, saying they had found one of the first two victims' homes and had brought a pair of hedge clippers for the castrations.
Martin told his story to police the next morning and Ruane was arrested with a pair of pruning shears and information on the last-known locations of the first two intended victims in the car, police said in the affidavit. New York State Police said Thursday that a "hand-written drawing of a depiction of Justin Bieber" was also found in the vehicle.
Staake and Ruane were arrested on charges of two counts each of conspiracy to commit murder and two counts each of conspiracy to commit aggravated battery.
Police are waiting for them to be extradited back to New Mexico, at which time they will be interviewed, said Lt. Robert McDonald. At that time investigators will decide what charges Martin may face, he said.
Bieber's management issued a statement that said, "we take every precaution to protect and insure the safety of Justin and his fans."
It was not immediately known if the suspects had defence lawyers.
