Five young people from West Malling have been arrested as police probe airgun pellets being fired at cars on the motorway.

Police issued a warning to motorists last month after a series of incidents on the London-bound section of the M20 at the junction with the M26.

Three cases happened between 6pm and 7pm on Tuesday, October 16, when the motorway was at its busiest with rush-hour traffic.

Police believe airgun pellets had been fired at moving vehicles - and at least one motorist has suffered injuries.

Now a 17-year old woman as well as two men aged 18 and 19 - all from West Malling - have been arrested on suspicion of causing criminal damage with intent to endanger life.

They were later released on bail until December 4, pending further investigation.

Today, a 15-year-old boy and a 20-year-old man, both from West Malling, were arrested and are in custody.

Ch Insp Jon Kirby, from Kent Police, said: "We are very grateful for the information we have received so far, which has allowed us to arrest five people. Our investigation is ongoing and I would continue to ask anyone with information to contact us."

Witnesses or anyone with information about who may be involved are asked phone police on 101.
