TWO drivers have had a lucky escape, after “reckless” people threw giant snowballs off a motorway bridge at their vehicles.

Police are sending out a strong warning to those who cause danger or damage to property through anti-social behaviour, after snow or ice was thrown off the Norton Road bridge onto the A1(M) near Baldock on Sunday night.

In one incident, which happened at about 9pm, a driver travelling northbound in a white Mercedes Sprinter van reported that snow or ice hit his windscreen, causing it to crack.

A second incident happened around 40 minutes later. This time, the driver, who was travelling in a blue Isuzu car, reported seeing three or four people throw a large snowball off the bridge, causing three cracks on the passenger side of his front windscreen.

North Herts safer neighbourhoods inspector Danny Lawrence said: “The danger of targeting vehicles in this manner is totally obvious. The offenders put these drivers at serious risk and could have caused someone to lose their life or even caused multiple fatalities.

“We will be stepping up patrols in the area and will be working hard to trace the suspects whose behaviour could be described at best as utterly reckless and without any regard for the safety of innocent members of the public.”

Neither driver was injured in the attacks.

Anyone with information can call the non-emergency number 101 quoting crime reference number G3/13/31.
