It is expected to be ‘bigger and better than ever’ with many of the favourite attractions on show and some new ones too.

For the first time there will be demonstrations from dog handlers covering both pro-active, pursuit trained Alsatians as well as from the waggy tailed Spaniels, which are trained to sniff out drugs.

The marine unit is also expected to be present along with police horses and demonstrations by officers from the Territorial Support Group, which deals with demonstrations and major incidents. A crime scene is also being planned by murder squad detectives.

Traffic police will be showing their latest cars and motorbikes. Whilst for history enthusiasts, the Met’s vintage vehicle fleet and uniforms from past years will also be on show.

Sutton’s custody suite with its charging counter and cells will be open with more groups being shown around at the same time to reduce queues. Also on show will be the Control Room, which hosts the Sutton Council funded CCTV system – with its bank of large monitors capturing images from the 80+ cameras located around the borough.

There will be many stalls including Sutton’s licensing team, volunteer police cadets and Neighbourhood Watch.

An estimated 4,500 visitors poured through the front gates at Sutton Police Station during the last main Open Day on Sunday, 2 June 2013 – beating the previous highest attendance in September 2010 when 3,700 visitors attended.

Safer Neighbourhoods Acting Inspector Emma Gulczynski, who is organising the event said: “We’re keeping our fingers crossed for good weather and bumper crowds coming through our doors to see how we work.

“It’s a great chance for residents to see behind the scenes and talk to officers about how we’re working to keep residents safe.”

The event is free and last entry is at 3.30pm.
