David Black was shot dead in November 2012
A man charged with murdering a prison officer in Northern Ireland is due to appear in court on Wednesday.
David Black (52) was shot dead as he drove to work along a motorway in Co Armagh in November 2012.
The father-of-two was the 31st member of the prison service to be killed in Northern Ireland, the first such murder in almost 20 years.
Detectives arrested a 33-year-old man in Lurgan in Co Armagh on Monday. He also faces charges of possessing a firearm with the intent to endanger life.
The accused will appear at Craigavon Magistrates' Court today, a Police Service of Northern Ireland (PSNI) spokeswoman said.
Mr Black, from Cookstown in Co Tyrone, was on the M1 motorway enroute to Maghaberry Prison in Co Antrim when he was shot at high speed.
The Toyota Camry car used in his killing was later found burnt out in Lurgan.
Two other men, one in Northern Ireland and one in the South, face charges linked to the purchase and movement of the Toyota Camry.
