A 40-year-old man has been arrested as part of the Ian Ogle murder investigation.
He was being questioned by detectives at Musgrave Street police station after being arrested yesterday on suspicion of murdering the 45-year-old east Belfast loyalist.
Mr Ogle was stabbed 11 times in the back during a frenzied attack in Cluan Place on January 27, dying in his son's arms.
Detective Chief Inspector Peter McKenna repeated his appeal for witnesses to the "horrific murder".
"Ian Ogle was subjected to a brutal attack. His skull was fractured and he was savagely stabbed 11 times in the back before being left to die on the street. His family deserve justice."
