Four men are being questioned about the brutal murder of a man who vanished after leaving a Co Antrim pub in October.
The body of Mr Hugh Cameron, 36, was found in the Skeagh River near Glenarm, Co Antrim, in mid November, 20 miles from where he was last seen alive in Carrickfergus.
Police said he had met a "brutal and violent death" sometime after leaving his local pub, the Joymount Arms.
It took DNA tests to formally identify the body when it was fished out of the river after being spotted by a passing motorist.
The Police Service said tonight they had arrested two men for questioning about the murder during the morning and two more later in the day.
Investigating officers also carried out an examination of a Carrickfergus pub - not the Joymount Arms - during the day.
