"They clearly aren't that bright."
Neil Cooper, Stratford District Council parks and properties assets manager, doesn't think much of the intelligence of the vandals who have recently attacked Victoria Park.
He says the vandals included identifying details in the graffiti they covered the park with.
They named their teacher and the time and date of an exam they were opting out of.
That information, combined with the fact they were caught on the CCTV cameras in the area, meant police were soon able to identify the culprits and talk to them. They are now being dealt with in the youth justice system. Graffiti isn't just laborious to clean up, says Neil, but costly as well.
