HUDDERSFIELD'S police chief has pleaded with people to supply detailed information about neighbourhood yobs.
Almondbury and Newsome have been blighted by vandalism and crime in recent weeks.
New play equipment at Greenside Infant School, Almondbury, was wrecked before children even had a chance to use it.
And, in an anonymous letter to the Examiner, a Newsome resident says pensioners are too scared to leave their homes because of the abuse and threats they receive from gangs of children on the loose.
Chief Supt Barry South, commander of Huddersfield police, said he was anxious to help tackle the problem.
But he said he could not do it without the co-operation of local people.
He added: "We need names and addresses. Who are these children, which school do they go to, where do they live?
"People do have problems, but they are not willing to come forward with intelligence that we can do something with."
Chief Supt South said the letter sent to the Examiner was typical of the sort sent to the police, in that it contained no material which officers could investigate.
"We need support from people to give us evidence," he said.
"If people have seen kids throwing stones, are they willing to make a statement saying so?
"If they do, then we can go to the suspects and confront them with it."
Chief Supt South said many of the disturbances were not solely the domain of the police.
"There are issues like getting children into school and parents keeping children under control," he said.
Chief Supt South said a new approach would be launched in July.
Teams of council and police officers would target trouble- spots.
Truancy will be tackled by police going to schools and speaking to head teachers about absent pupils. "There are a myriad of activities we can undertake," he said.
"It is not that they are not going on now, but there needs to be more structure, so that people understand it is not just the police's problem," said Chief Supt South.
