‘Passing of Alan McQuillan OBE
‘Former PSNI Assistant Chief Constable Alan McQuillan OBE has passed away peacefully following a four year battle with prostrate cancer.
‘Despite graduating as an astrophysicist with no policing career plans, a series of events and his overwhelming care for others took him into policing.
‘Alan cared deeply about protecting and helping every community across Northern Ireland, even when this meant personal sacrifices


‘In his role as a senior police officer, he was unafraid to take hard decisions to achieve peace for everyone, even when the consequence would be as significant as collapsing the government.
‘His work in setting up and running the Assets Recovery Agency (now within the National Crime Agency) hammered major blows to paramilitaries and organised crime across Northern Ireland, the rest of United Kingdom and internationally.
‘His actions stopped hundreds of millions of pounds from being used to harm and murder people by criminals and terrorists.
‘A true professional, with integrity, honesty and a sense of fairness which was evident in every aspect of his career; a likeable and popular man who was always ready to provide advice and guidance to all who needed and asked for his support, even long after his retirement.
‘Alan is survived by his loving wife Heather, daughter Jane and son Andrew who ask for privacy at this time.
‘There will be a service of thanksgiving at St Columba's Church, Knock Road, Belfast on Monday 20th October at 11am’.
