Police have condemned yobs who have hurled bricks and rocks at 22 buses travelling around Gravesend.

Bus company Arriva is offering a £200 reward for information leading to the arrest and prosecution of those responsible following a spate of attacks in recent weeks.

Acting chief inspector Patrick Holmes, Gravesham District Commander, said: "This is extremely serious, the youths doing this who will be from the local area, are putting many people’s lives at risk.

"I would urge anyone who knows who they are to urgently encourage them to give themselves up, or to report them to us so we can speak to them before there is a tragedy "

An Arriva spokesman said: "Unfortunately windows were recently broken on services 483 and 423, which were not the first incidents of their kind.

"We are working closely with the police and are offering a £200 reward for any information leading to the successful arrest and prosecution of the perpetrators.

"The safety of our passengers and drivers is always paramount."

Anyone with information is asked to call 01474 366149, quoting crime reference XY/54807/17, or the anonymous Crimestoppers hotline on 0800 555111.
