Masked armed raiders burst into the home of a terrified Doncaster man and threatened him with a piece of piping and a knife.
The 51-year-old victim was in his bathroom when the three-man gang struck.
He was forced into the kitchen of his home in Thorne and assaulted before the men fled with cash.
As detectives launched an investigation, community leaders today spoke of their shock at the attack and urged other residents to be vigilant.
Thorne councillor Martin Williams said: “It is very unusual and extraordinary for something like this to happen in Thorne. I hope the police manage to catch them.
“They can lock them up and throw away the key as far as I am concerned. They need a good few years and proper punishment for this.
“If anyone has information then they should tell the police.”
Thorne and Moorends town councillor Carol Blackham added: “I’m really surprised to hear this. It’s certainly not something that happens often in this area.
“It seems like a targeted attack.
“How horrible. “This is a warning for people to make sure their doors are always kept locked.”
Councillor Eddie Dobbs, civic mayor of Doncaster, said: “I am shocked to hear this because crime in general has actually been going down in Thorne so this has come out of the blue.
“It just shows you must keep your doors locked even when when you are in.”
The victim, who has not been identified by police, was in his flat at Rainbow Close when the burglary happened on Sunday at 6.30pm.
The gang entered through an unlocked front door.
A spokeswoman for South Yorkshire Police said: “One raider threatened the man with piping and hit him at the top of his thigh, causing bruising, while another carried a small knife with a four-inch, curved, silver blade.
“The burglars searched drawers and made off with £340, running in the direction of Southfield Road.”
The man who assaulted the victim is around 5ft 10ins tall, slim and with short, ginger hair.
His accomplice, who was carrying the knife, had short, dark hair, was aged in his early twenties and of slim build.
A third man was slim and also had short, dark hair and was aged in his early twenties.
Anyone with information should call South Yorkshire Police on 101 and quote incident number 961 of January 19.
