Inspector Aled George said: “Distracting motorists while driving is very dangerous and throwing items, such as eggs, at moving vehicles could potentially result in a serious accident.
“We have already been provided with the names of some of those involved and these persons will be dealt with formally.
“I would urge anyone with any further information relating to the identity of those responsible for the anti-social behaviour or anyone who has any CCTV footage to call us on 101 or contact local neighbourhood officers.
“We’d like to remind youngsters that throwing eggs may be considered as criminal damage or causing a danger to road users.
