A man has been arrested after an elderly couple were found dead in their home in Co Armagh.
The couple, aged in their 80s, had been stabbed to death.
Their bodies were discovered by their daughter and son-in-law who called to the house at Upper Ramone Park on the outskirts of Portadown.
A short time later, a 40-year-old man was arrested by police about a mile from the scene.
The suspect is being questioned by detectives in custody.
Forensic officers are at the scene in the quiet residential street near Craigavon Area Hospital.
PSNI Chief Inspector Geoffrey Boyce said: "Police investigating the circumstances surrounding the suspicious deaths of an elderly man and woman in the Craigavon area have arrested a 40-year-old man."
Detectives are still working to establish a motive, with one line of inquiry understood to be the pensioners were killed in a violent burglary.
DUP representative David Simpson said they were found by a relative.
"The couple were in their 80s and tragically lost their lives in their own home today," he said.
"A family member was the first to find them and we can only begin to imagine the shock, heartbreak and pain this has caused.
"It is important the family receive time and space to grieve the loss of two parents in such tragic circumstances."
Local SDLP councillor Declan McAlinden said the couple were the victim of a "heinous crime".
"The entire community is just in shock that someone could murder an elderly couple in their own home like this," he said.
"I would appeal to anyone with any information or who saw anything suspicious in the area to come forward to police as soon as possible," he added.
