In a statement on Thursday night, a PSNI spokesperson said: "Detectives investigating the murder of 39-year-old Shane Whitla in Lurgan on Thursday January 12, have searched a house in the Lurgan area and arrested a 29-year-old man this evening, Thursday January 20.
"He has been taken to Antrim Serious Crime suite where he remains in custody for further questioning."
Earlier on Thursday, police were granted an extension of 27 hours for the further detention of a 28-year-old man who was arrested on suspicion of murder on Wednesday.
On Tuesday, police released CCTV of two gunmen in an appeal for information as what the PSNI have described as a “cowardly and despicable attack”.
Detectives say they believe Shane Whitla was shot on Thursday January 12 in an alley off Woodville Street in the town before staggering to Lord Lurgan Park where he died.
Police say information, including photos, CCTV and dash cam footage, can also be provided to police through the Major Incident Public Portal at https://mipp.police.uk/operation/PSNI23S01-PO1.
