Extra patrols were being carried out in a Sheffield suburb yesterday after yobs hurled bricks and bottles at a police car and threw fireworks at other motorists.
Youths struck on Bonfire Night - setting up barricades in the middle of Abbeydale Road to target vehicles which were forced to slow down.
Police also received a number of hoax calls believed to have been aimed at luring officers to the area to target.
As the trouble escalated, police chiefs ordered extra police officers into the area to break up groups of yobs but no arrests were made.
Inspector Ian Stubbs, responsible for policing the area, said: “A police car was driving down Abbeydale Road when a group of about 20 youths ran into the street and threw missiles at the car - bottles and bricks,” he said.
“The driver’s side window was smashed, as was the passenger side rear window. This was an act of criminality, not anti-social behaviour.
“We also had a series of what we suspect were hoax calls trying to draw us in under false pretences. We then started to get reports from the public of a barricade across the road, acting as a chicane that drivers had to slow down to get through. As they slowed they were targeted with fireworks.
“Thankfully there were no injuries reported but nevertheless this was frightening and serious.”
Coun Nikki Bond, who represents the Nether Edge ward, said: “We are extremely disappointed - we have worked incredibly hard to prevent this.
“This behaviour is completely unacceptable - there is a clear distinction between anti-social behaviour and plain criminal disorder, which this is.
“Throughout the year there have been incidents of brick throwing and I am amazed there hasn’t been a serious incident yet.”
Anyone with information about those responsible should call 101 or 0800 555 111.
