A man was rushed to hospital after being found in a pool of blood following a knife attack on a Sheffield street.
The 21-year-old was found injured on Brimmesfield Close, Arbourthorne, on Sunday night and was in a serious but stable condition yesterday.
Residents said they heard raised voices and shouting before police and paramedics arrived.
Police cordoned off a section of the street where the casualty was found while forensic experts examined the scene yesterday.
The officers, dressed in protective white suits, were also seen carrying out an examination of a flat close to where the injured man was found.
Yesterday blood staining was still visible on the pavement.
Mark Charlton, aged 51, who only moved to the street three weeks ago, said: “I just heard a ruckus and looked outside and could see a group.
“I could hear people shouting and saw a man with blood on his top, but I never for one minute thought he had been stabbed, I thought maybe he had been punched.
“I just thought it was a run of the mill argument, nothing as serious as a stabbing. I saw the police arrive and that was all.
“I just keep myself to myself and don’t get involved in things.”
A mum-of-two, who lives close to the crime scene, said: “I was in bed when I heard a commotion and looked outside and could see a group of young people - lads and lasses - outside in a big group.
“There was shouting and raised voices and then the police came.
“Nothing out of the ordinary normally happens here, so it is worrying that somebody has been stabbed so close to where I live.
“It’s not nice for people to have to walk past blood staining on the pavement.”
A South Yorkshire Police spokeswoman said officers had made two arrests on Sunday.
“Emergency services were called at around 10pm on Sunday to Brimmesfield Close. “A 21-year-old man was found with what are believed to be stab injuries,” she added.
“A 22-year-old man and a 31-year-old man have been arrested on suspicion of public order offences and are in police custody.
“A cordon is in place in Brimmesfield Close while police continue their inquiries.”
The attack came two days after an 18-year-old man was found with stab wounds on Firth Park Road, Firth Park, at 9.30pm on Friday.
He was taken to hospital in a serious condition, where he remained yesterday.
His condition was described as stable.
Three 20-year-old men were arrested on suspicion of attempted murder.
Witnesses to either incident or anyone with information should call South Yorkshire Police on 101 or Crimestoppers on 0800 555111.
