The man, who has not yet been named, was pronounced dead at Bassetlaw Hospital on the evening of Saturday 6th April 2013.
Notts Police has now launched a murder investigation, and four teenage boys have been arrested in connection with the death.
They remain in custody this afternoon. Three are aged 15, and one is 16.
The incident happened in Worksop’s main shopping street, Bridge Street, at 7.30pm - in broad daylight.
Local people spoke of their shock at what had happened, as forensic officers collected evidence at the scene on Sunday lunchtime.
“I didn’t know anything about it until I saw the police here this morning,” said one elderly woman, who did not want to be named.
“It’s very upsetting and absolutely tragic for the man who has died - and for his family.”
Another man, from Dinnington, also said the events were ‘tragic’.
“It’s tragic but I can’t say I’m particularly shocked. This kind of thing is happening more and more in Worksop. It’s a sign of the times.”
“But I am very sorry for the man and his loved ones.”
