A police force which has been inundated with phone calls about snowballs has asked people to only ring if strictly necessary. Switchboard operators at Nottinghamshire Police have received hundreds of calls about people throwing snowballs since the wintry weather hit the region. A spokesman for the force said between 9am on Tuesday and 7.45am on Thursday around 120 calls had been sent through to the control room from switchboard operators. He said those calls were thought to have been of a serious enough nature to make control room officers aware and many more will have come through to the switchboard which it was not necessary for police to be involved in. He said: "We are advising people to only ring us if there is an incident with snowball throwing that it seems only police can deal with.
