A Banbridge pensioner, attacked in his home at the weekend, was targeted just a week after the heartbreaking loss of his partner of almost 30 years.
A 47-year-old man has been arrested in connection with the weekend incident.
The suspect, who was detained on suspicion of burglary and assault, remained in custody on Monday night.
Tommy McDowell (88) was pinned to his bed in his Granville Gardens home by two masked intruders, who then fled when he fought back. The pair forced their way into the house at around 7pm on Saturday.
The elderly man was upstairs at the time when the two suspects entered his bedroom.
Tommy said: "I was lying on top of the bed having a wee doze and I heard someone in the room. I thought it was my son Gary or daughter Mandy but when I got up I saw the figure of a stout fella and there was a young fella with him."
The heavier of the two men pinned Mr McDowell on his bed and, as the victim tried to defend himself, he was injured in a struggle.
"I put my foot against his stomach and pushed him back against the wardrobe but he caught my arm to stop me throwing punches," he added.
The robbers made off with his wallet containing £10, gardening equipment and two phones, which they later discarded.
Police were alerted after one of Mr McDowell's daughters arrived at the house a short time later.
He was treated for the cuts and bruises at Craigavon Area Hospital and is now being cared for by family members.
Mr McDowell's relatives believe he was deliberately targeted by thieves looking for drugs through a death notice for his beloved partner and lifelong friend Eileen Humphries, who died of cancer on February 12.
The pensioner has been left badly shaken by his terrifying ordeal and won't be able to return to his home. He is now preparing to move closer to his family.
Gary Humphries blamed drug addicts for the vicious assault and burglary inflicted on his late mother's partner.
He said: "I'd like to make the public aware that these people are targeting the vulnerable and sick, thinking prescription drugs are on the property. I would appeal to people please lock up all medications, especially morphine for cancer patients.
"These people have no integrity or morals whatsoever and don't care who they hurt to get a fix. Nothing will stop these people, only the long arm of the law."
Mr Humphries added: "As you can imagine the last thing he needed was this whilst still mourning the loss of his partner of 30 years - my mother. I appeal for anyone who has any information to contact the PSNI and give them the information no matter how small you think."
Ulster Unionist Alderman Glenn Barr condemned the culprits. He said: "My thoughts are with Tommy, Gary and their family at this time. I am absolutely gobsmacked at the level that these people have stooped to.
"It seems they were after prescription drugs. I would urge people to remain vigilant and to lock their prescription drugs away."
Police branded the attack "nasty and despicable" and appealed to anyone with information to get in touch with detectives in Lurgan on 101, quoting reference number 1584 of 20/02/21.
