A young driver spoke of her shock after a stone was thrown at her car – smashing a window – while she drove on the main road through Diss.

Rozanna Goodwin said she was lucky not to be seriously injured after the piece of granite was hurled at her car as she travelled along Victoria Road in the early hours of Sunday morning.

The 19-year-old, who lives in Garboldisham, had picked up her sister and friends from a night out in Norwich when the driver's side window of her Ford Fiesta was smashed at about 2.30am near the junction of Skelton Road.

Police are appealing for information after the incident and the young driver is warning other motorists to be on their guard.

Miss Goodwin, who works as a nanny in the area, said she was driving home when the rock, which was about the size of a golf ball, smashed her window and struck her, causing her shoulder to swell up.

The driver and her passengers were also showered with shards of glass.

She added that she did not see the offender and feared that they might strike again.

'It is a really idiotic thing to do and it is lucky that it did not hit me in the face. Unfortunately, the people that did this will not be caught and it could happen again. It is lucky I'm young and I'd hate to see something like this happen to an older driver,' she said.

A spokesman for Norfolk police said they were called at 2.20am on Sunday after the car window was smashed in Victoria Road.
