A six-month blitz on anti-social behaviour in the Abbeydale Road area has been announced by police.
Officers have put a dispersal order in place following pressure from businesses and the public for police to stop groups gathering and being disruptive.
Sarah Jameson, owner of Jamesons Cafe and Tearooms in Abbeydale Road, said: “We’ve only been trading for 12 weeks and we were broken into two weeks ago.
“They got into the shop, then into the office and stole some float money, stole my laptop and smashed all the locks on an antique desk.
“It was awful. We’re a small business trying to make our way.”
She also said the tearoom is disturbed by youths on quad bikes going down the road during the day, and she often sees youngsters congregating at night.
The order, which will be in place until November, means any group causing problems will be asked to leave the area.
Youngsters out without an adult between 9pm and 6am will be taken home or to a safe place, and those ignoring orders could be arrested.
The order will apply to everywhere between Bramall Lane, part of Sharrow Lane, Wostenholm Road down to Archer Lane and just beyond Carter Knowle Road.
South Yorkshire Police Sergeant Dean Hill said: “There has been an escalation in problems in various locations, such as Broadfield Park and St Peter’s Church, caused by a certain number of youths.
“This includes criminal damage, verbal abuse and the risk of accidents.
“We hope that the order will achieve a reduction in the anti-social behaviour that has caused difficulties for residents and businesses, and improve confidence.”
