Police are hunting two robbers who struck in Sheffield - attacking a man in his home and threatening shop workers with a knife.
In the most recent incident on Christmas Day, a 61-year-old man answered a knock at his door and was confronted by a man who assaulted him before stealing cash and a PlayStation 3 games console.
Police said the robber struck on Reney Crescent, Lowedges, at 10.30am and left his victim seriously injured.
Detective Inspector Richard Partridge, of South Yorkshire Police, said: “We believe that the suspect deliberately targeted this man’s house, forcing his way into the property and injuring a vulnerable member of the community before stealing valuables.
“This crime took place on Christmas Day in broad daylight and I’d urge anyone living in the area to cast their minds back and think about whether they noticed anything suspicious.
“If you’ve been approached by anyone trying to sell a games console, or have been made aware of a PlayStation 3 that is up for sale, we’d like to know about that too.
“If you have any information that could help us catch whoever is responsible for this dreadful act, or information about similar offences perhaps, please get in touch.”
Two days earlier a robber struck at Pricewise on Birley Moor Place, Sheffield.
He threatened staff with a knife while demanding cash.
The man, captured on CCTV, was white, around 6ft tall, between 25 and 30-years-old and wore a dark blue parka style coat.
Witnesses to either incident or anyone with information should call police on 101 or Crimestoppers on 0800 555111l.
