Detectives from Serious Crime Branch investigating the sectarian murder of Paul McCauley in Derry have arrested a 24 year old man in Derry today.
Paul died last month in a care facility almost nine years after an attack in July 2006.
Paul was 29 and attending a summer BBQ at the rear of a house in Chapel Road on 15 July 2006.
At 3.20am on 16 July, only three people remained at the BBQ.
A group of up to 15 people came from out of the bushes and attacked Paul and two of his friends. After the assault the group made off in the direction of Irish Street.
The suspect was arrested in the Fountain area of the city this morning and has been taken to Strand Road police station for questioning.
Detective Chief Inspector Michael Harvey, from Serious Crime Branch, said: “After Paul’s tragic death last month, the investigation has taken on a renewed impetus.
“We are following a definite line of enquiry and we are grateful to those individuals who came forward with information in the immediate aftermath of Paul’s death.”
