PSNI are investigating the 1976 murder
A man was arrested in London today for questioning about a sectarian murder in Northern Ireland more than 35 years ago.
He is aged 60 and originally from Belfast.
The man is being held for questioning about the murder of Paul McNally, 26, a Catholic who was shot dead by loyalists as he left a bookmaker's shop on Belfast's Crumlin Road in June 1976.
It is believed two gunmen opened fire on a group of men who were leaving the bookmaker's.
Mr McNally and another man sustained serious injuries.
Mr McNally, a plumber, died two days later in hospital. He was married and had a four-year-old daughter and a five-month-old son.
Detectives from the Police Service of Northern Ireland (PSNI) serious crime branch, assisted by officers from the Metropolitan Police Service, interviewed the man at a police station in London.
Police said the investigation was re-opened following the receipt of information and a number of preliminary inquiries.
In February, a man was arrested in Belfast and later released pending a report being sent to the Public Prosecution Service.
