A secret snapshot of loutish behaviour was recorded in Sussex yesterday after the Home Office ordered a 24-hour "census" of antisocial behaviour.

Behaviour the police, local authorities and other agencies were asked to measure ranges from vandalism and rowdiness to street drinking and begging.

The exercise was not announced in advance. Yesterday was chosen for the count because it was thought to be an average day - mid-week and in term time.

Ministers want to know the impact yobbish behaviour has on individuals, communities, businesses and local areas.

The Home Office will also be able to measure the impact on over-stretched public services such as the police and medical staff.

Police, fire service, housing associations and local authority housing, cleansing and education departments took part.

A Home Office memorandum said: "We have no idea how much antisocial behaviour goes on.

"A one-day count will start to tell us about the overall amount and nature of reported antisocial behaviour in England and Wales, and give an insight into any regional variations."

The census will measure antisocial behaviour under headings including drug misuse and dealing, street drinking and begging, prostitution, abandoned vehicles, vehicle-related nuisance, noise, rowdy behaviour, criminal damage and litter offences.
