Violence flared on a Dearne street at the weekend amid claims a sex offender had been unmasked as living among families and close to a school.
Police made four arrests during a disturbance on Merrill Road, Thurnscoe, after a group of neighbours had gathered outside a property just before 6pm on Friday night.
A group of neighbours gathered at the scene the following morning told how a group of about 100 people had amassed outside the property, believing the male resident had recently been released from prison for sex offences.
The windows of two cars outside a property had been smashed during the confrontation.
Residents said the man claimed it was a case of mistaken identity and he would be contacting police.
Mum-of-two Christine Hill, 32, of nearby Whin Gardens, said: “It was all a bit chaotic. The police took the man away and also arrested a couple of residents.”
Father-of-five Tony Smith added: “We found out some information about him and we were all concerned.
“There are a lot of families around here and Gooseacre Primary School is just around the corner.”
Residents had raised a petition of about 400 people in a bid to get the man evicted. South Yorkshire Police have not named the man in question and would not give any details about the nature of his alleged crimes.
A spokeswoman for the force said: “Police were called to a disturbance on Merrill Road in Thurnscoe on Friday, 30 August, at around 5.55pm.
“A number of people were out on the street with a small group shouting at each other. “Four people were arrested, two women, 38 and 36-years-old and two men, 48 and 43-years-old, for public order offences.
“The two women and the 43-year-old man were cautioned and released. The 48-year-old man was re-arrested for a recall to prison following information received by police at around the same time of the incident that he had breached the conditions of his licence.”
