A delivery driver who caused terror and injury by throwing rocks at motorists "for fun" across the Weald has been jailed for 10 years.

Glynn Williams, 37, was said to “not give a hoot” to the consequences of his actions as he hurled the missiles while passing oncoming vehicles at speed.

Judge Martin Joy said: "The impact of this series of offences could have been fatal. This was sheer wicked activity on your part."

Many of the drivers targeted were women, some with young children in their vehicles.

Two drivers were injured by the large rocks. One mum was struck in the face.

The rocks shattered windows or left dents in bodywork. One victim whose windscreen was smashed thought she had been shot at and searched for a bullet.

Williams, who worked for United Parcel Service, was convicted of 14 offences of damaging property being reckless as to whether life was endangered, one of criminal damage, one of assault causing actual bodily harm and one of common assault.

Judge Joy had warned he was considering a prison term of at least 10 years.

Maidstone Crown Court heard he was the only UPS driver responsible for the patch covering the villages of Sissinghurst, Goudhurst, Cranbrook, Benenden, Biddenden, Rolvenden and Sandhurst.

Delivery records placed him dropping off parcels in the area at the time.

The incidents occurred between January and August 2015, with several on the same day and the victims specifically identifying a UPS or brown-coloured van.

At the start of his trial, prosecutor Alex Rooke said Williams had “a habit for whatever reason” of chucking rocks at vehicles, and did not “give a hoot for the blindingly obvious risk to life and limb”.

Williams, of North Street, Dartford, was arrested at work but denied being responsible.

He bizarrely told police that on 15 occasions he randomly found rocks in his vehicle.

He was cleared of one offence of damaging property being reckless and one of assault causing actual bodily harm.

Williams, who did not give evidence, has previous convictions for assaulting police and possessing cannabis.

Several victims gave evidence about how their vehicles were hit.

Jennie Ivinson was struck in the face as she drove with her two young children towards Sissinghurst just before 1.30pm on August 18.

The missile, described as "a throwable chunk", was later found on the back seat.

Ms Ivinson suffered a black eye with cuts and cheekbone bruising.

A rock smashed through Grace Rowson’s Toyota Yaris, forcing her to pull over and look for what she thought was a bullet on April 7, 2015.

She had just driven past Benenden Hospital on her way to Headcorn when she saw an oncoming brown-coloured van.

“He looked quite cocky. I thought he was going to hit me, crash into me," she said.

“But instead, as he came near me, there was this popping noise and I genuinely felt, and believed, I had been shot at.

“I stopped immediately. There was a hole in my windscreen at face level.

“I got out the car to see if anything was on the road but I didn’t see anything. I was looking for some big stone, or bullet even.”
