Voluntary police officers have been tackling illegal drivers, anti-social behaviour and drug dealing.

More than 100 special constables were out in force across Hertfordshire between May 31 and June 2 to mark National Special's Weekend.

This is what constables got up to over the weekend.

In Watford, they carried out proactive, high-visibility patrols to help tackle emerging crime trends – including patrols of Cassiobury Park where intelligence had been received that drug dealing was taking place. Reassurance patrols were also conducted in the town centre, which also resulted in five traffic offence reports being issued for driving offences.

Officers conducted high visibility patrols in hotspot areas across Hertsmere, to help tackle emerging crime trends.

Three people were issued with traffic offence reports, including one driver who was caught travelling at 61mph in a 30mph zone in Croxley Green. Elsewhere in Three Rivers, foot patrols were carried out in Rickmansworth town centre.

While a joint ANPR operation took place in St Albans and Dacorum to target travelling criminals and people committing driving offences. Four vehicles were seized for having no insurance or for being driven without a licence. Seven traffic offence reports were also issued.

Special constables have full police powers, uniform and protective equipment and work alongside the regular force. They get involved in a number of frontline activities.
