A MURDERER who shot dead his bitter enemy on a street has had his face slashed open in a prison revenge attack.
Derek Felvus, 26, was ambushed by another lag allegedly hired by gang rivals Murder of Graham “Kermit” Williamson.
And he was left scarred and bloody after the ambush at nearby HMP Shotts.
A source said: “Felvus is a marked man.
“He was seriously injured, with a large wound torn from his face.
“It’s no secret that people are out to get felvus, and there’s no shortage of lags on the inside who are willing to throw in attacks for the right price.”
Felvus was part of a crew of three jailed for Graham’s murder in August 2020.
The father was shot in the back at close range with a sawed-off shotgun outside his home amid a “toxic feud”.
It came after Felvus was filmed hiding in a Chinese restaurant after a previous confrontation in a video shared on social media.
The “embarrassed” Hardman and his accomplices then executed Graham.
We can also reveal that Felvus had his sentence extended to three months in April after he was caught with an illegal cell phone SIM card in his cell.
