PROLIFIC rapist Reynhard Sinaga was the target of an attack behind bars in an alleged planned hit by prison vigilantes.
The fiend — convicted for 159 sex offences including 136 rapes of young men — is serving life with a minimum of 40 years.
He is said to have narrowly avoided serious injury in the attack at HMP Wakefield in July, which is said to have been halted by prison guards.
A source told The Sun: “Sinaga is arrogant and universally loathed. He is a clear target in prison because of his depraved crimes.
“He was seconds away from extremely serious harm. He is in danger.”
Sinaga came to the UK as a student from Indonesia in 2005 and spent more than a decade drugging and raping men at his Manchester flat.
He was caught after a victim woke during an assault in 2017.
Cops later found thousands of hours of sex assault clips on his phone, sparking the largest rape investigation ever.
Jack McRae, 32 — who has since been moved to Frankland prison in Co Durham — has been charged with attempted GBH with intent of Sinaga, 41.
He is charged with the same offence against child killer rapist Wilbert Dyce at Wakefield in 2023.
McRae is also accused of ABH on lags Sayed Taheri, Patrick Harrington and Andrew Gillis, and assaulting an emergency worker.
Another man, Andrew Beadie, now at Long Lartin, Worcs, is jointly charged with the alleged attack on Taheri.
McRae is due before Leeds JPs on Tuesday.
