Two juveniles were being questioned by police today after the death of a security guard at a shopping centre on the outskirts of north Belfast. The guard died at the Abbey Centre at Newtownabbey, Co Antrim at around 2.00pm. The PSNI said they were investigating the death about an hour after the shopping mall opened for Sunday trading. They then revealed the male juveniles had been taken to a local police station where they were helping police with their inquiries.
