Police investigating the brutal murder of an elderly couple in their Portadown home have been given extra time to question the chief suspect.
The 40-year-old was arrested in the aftermath of the attack on Friday. On Sunday police went to court to apply for extra time to continue their questioning, which was granted by a judge.
Michael and Marjorie Cawdery - both aged 83 - were found murdered in their Portadown home. It's understood they had both been subjected to a savage knife attack.
Mr Cawdery was a retired veterinary researcher, and had a long and distinguished career in his profession.
Educated in Nairobi, at Portora Royal School and at Trinity College Dublin, Mr Cawdrey - along with his wife - had been directors of veterinary firm Cawel Ltd, which was dissolved in 2011.
He published many well-regarded research articles in a wide range of academic journals in his field.
Just a week ago, he had written a letter to the British Medical Journal, examining the impact of the Ransomware virus which infected NHS computers.
