A squad of anti-litter officials has been given instructions to film suspects on the street - even before they have done anything wrong.
The team of 11' environmental enforcement officers' has been equipped with mobile phone cameras and told to use them to film people they think may be about to drop litter. The use of cameras to record individuals who have committed no crime or offence has generated a row over the spying powers of local councils and the growing willingness of officials to stretch them to the limit.
