A CONTRACT killer serving life for murdering a rival drug dealer has been warned he risks being attacked in prison.
'Pistol' Peter Greer was issued with the death threat over Christmas by loyalists linked to dead UDA hitman Stevie McKeag.
The 43-year-old was notified that he is being targeted in Maghaberry jail and should take the warning seriously.
Although the Prison Service does not comment on individual cases, sources at the jail were more talkative.
One said: "Greer was told at Christmas of the threat against him from a group calling itself the Real UFF. It was serious enough for him to be officially warned that he is at risk."
Loyalists believe the threat is connected to ex-UVF pipebomber Francis 'Franky' McNally, who is nearing the end of an 11-year jail sentence for a sectarian attack on the home of a Catholic grandmother.
The 33-year-old was moved to Magilligan Prison after clashing with Greer in Maghaberry. McNally accused the convicted murderer of plotting to have him killed behind bars.
"Franky has made public threats against Greer, saying he is going to 'do him' the first chance he gets," added our source.
"He'd also be on good terms with some of Stevie McKeag's old UDA mates and the feeling is that he has put them up to threatening Greer."
McNally has also accused Greer of trying to implicate him in the attempted murder of drug dealer North Lucas, who survived being blasted with a shotgun in Comber, Co Down, last March.
An effort was made to hide the weapon in the garden of one of McNally's relatives, but abandoned at the last moment because of a passing PSNI patrol.
Stephen 'Dick' Dempsey (59) has since been charged with attempting to murder Lucas - an allegation he denies.
The assassination attempt occurred just weeks after Lucas was freed from prison having served a sentence for running a cannabis factory.
Prior to his release Greer warned him that he owed £400,000 for the lost drugs and he would be killed if the money was not paid.
Despite being behind bars, Greer continues to exert control over criminality, particularly drug dealing, in the north Down area.
The former UVF member is nine years into a 20-year life sentence for the 2011 murder of rival cocaine baron Dougie Morrison, who was gunned down in his Bangor home.
Greer and pal Jamie Smith (42) carried out the cold-blooded killing following a row over drugs turf.
