FIVE people have been arrested in an investigation into cars being shot at in Wrotham.
Three vehicles have been damaged and a driver injured in attacks on vehicles on the M20.
They were travelling near Junction 3 of the London-bound carriageway of the M20 when they were hit by air gun pellets.
The attacks happened between 6 and 7pm on October 16, smashing windows and denting bodywork.
In one incident the near side of a Peugeot 206 was struck and its front passenger window smashed as it passed under a bridge half a mile before the turn off to the A20.
The driver's face was cut by the shattered glass and he was hit in the arm by a pellet, forcing him to pull onto the hard shoulder and call for help.
In a second attack, where the M20 meets the M26, an Audi A4 was hit on its rear, causing a large dent, while a back passenger window of another car was shattered in a third shooting.
A 17-year-old woman and two men, 18 and 19 years old, all from West Malling, were arrested on October 30 on suspicion on criminal damage with intent to endanger life.
They were released on bail until December 4, pending further investigation.
On Friday, a 15-year-old boy and a 20-year-old man were also arrested, and are in custody.
The stretch of road where the attacks occurred is used by people driving home to Wrotham and nearby Borough Green and West Malling after work and police are concerned at the risk the shootings posed to drivers.
Kent Police chief inspector Jon Kirby 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 should contact Inspector Kirby at Kent Police on 101 or Kent Crimestoppers anonymously on 0800 555 111.
