A dead woman's ashes were thrown onto the floor by thieves who ransacked her home just one month after her funeral.
Crooks broke into Yvonne Towey's home in Retford Road, Woodhouse Mill, on Monday afternoon when her husband Kevin, 64, was out.
Relatives of Yvonne, who was cremated four weeks ago after losing her battle with cancer on March 15, said they are 'disgusted' at those involved in the raid.
Her husband, a retired firefighter who was forced to give up work after his leg was shattered in an explosion during a blaze, described the raiders as 'the lowest of the low'.
He returned to his house to find all the couple's belongings all over the floor, including a container with his beloved wife's ashes inside.
Her laptop computer, phone and purse were missing along with £70 in 50p pieces, a TV recorder and two watches.
Kevin said: "I am just glad this happened when it did and not a few weeks earlier as Yvonne would have been downstairs when they broke in as her bed was there. She would have come face to face with these low lives but would not have been able to have done anything about it because she was so ill.
"It is absolutely disgusting that people think that they can break into your home and take things that you worked for all your life. They are the lowest of the low.
"I am feeling bad enough at losing my wife and then this happens. To have seen the container with her ashes in tossed aside like it was nothing was sickening.
"The place was ransacked, upstairs and down. Drawers had been emptied, pictures were on the floor. They had been through everything."
He said he is now wary of leaving his home.
"I don't know if they saw me leaving the house or of they had been watching me and that feeling does make you wary of going out," he said.
"I hope they catch who did this and that they are stopped from putting anyone else through all this."
A South Yorkshire Police spokeswoman said: "A burglary was reported on Monday at a property on Retford Road in Woodhouse Mill.
"It is believed forced entry was gained between between 11am and 1.30pm. A number electrical items, jewellery and cash were stolen.
"Detectives are investigating and would urge anyone with information to please call."
Anyone with information should contact South Yorkshire Police on 101 or Crimestoppers on 0800 555111.
