Police deployed a helicopter on Tuesday night after reports of a man running around with a knife.
Following an air-borne and ground search the man was arrested by officers in the Lurgan area.
Police said the man in his 20s was spotted running around with a knife in the Victoria Street area of north Lurgan.
The PSNI tasked a helicopter to search for the man who was discovered, cornered and arrested for possession of an offensive weapon.
Police added there had been a bench warrant out for his arrest and he is currently in custody.
A PSNI spokesperson said: “This was all made possible due to some really accurate information from members of the public, who gave great descriptions, directions of travel and made it quite a simple task for the Chopper Coppers to find him.
“Great work by all, starting again with you – the public.”
