Police are hunting for a gunman after two cars were shot at while waiting at traffic lights in Garston.

A silver Chrysler estate and a black Vauxhall saloon were shot at by a gunman armed with what police believe is an air rifle while waiting at traffic lights at the A405 junction along St Albans Road yesterday.

The rear windscreen of the Chrysler was smashed and the Vauxhall was damaged as the gunman shot at the stationary car.

One of the victims reported on Facebook: "When my rear screen was struck, which I initially thought was a loose stone from a passing vehicle. A few seconds later, it was struck again, this time shattering the glass into the car.

"At this point I ran the lights not wanting to wait for a third hit. I then called the police and after they searched my car they found a gun pellet behind the front passenger seat.

"The terrifying thing is that the only way that could travel there is through the window and over my children’s heads. I would like this person to be found now before someone gets seriously injured."

No one was hurt in either of the incidents, which occurred at 7.30pm and 7.35pm.

Anyone with any information in relation to these incidents should contact Hertfordshire Constabulary via the non-emergency number 101.
