“A convicted killer locked up in New Mexico plotted to have Justin Bieber murdered and castrated ... but for some mysterious reason, he threw a wrench into his own plans -- this according to a local news report in New Mexico.

Martin reportedly told police the plan was to kidnap Bieber and his bodyguard and strangle them with paisley ties, Martin's calling card. Ruane was then going to castrate them.

According to KRQE, Martin is obsessed with Bieber and even has a tattoo of Bieber on his leg.

But for some reason Martin blew the whistle on his accomplices -- and Staake was arrested in Vermont on outstanding warrants before carrying out the deed.

Ruane made it to NY with a stash of tools -- including pruning shears -- but according to the report police intercepted him before anything happened, and placed him under arrest.”
