Over the last few weeks, calls from members of the public have helped arrest suspected car thieves, raised the alarm on possible rogue traders and ensured that drugs and weapons have been taken off the street.
In Peterborough, on February 22, a member of the public called police after spotting a man riding one bike but pushing another - which had no front wheel - along at the same time.
A man was later found by officers in the area with a hammer, pliers and a chisel, together with the alleged stolen bike. A crime has been raised for bike theft.
The Stay In, Speak Out campaign highlights the fact that the Covid-19 crisis has led to people changing where they work and more people spending time at home.
Superintendent James Sutherland said: "Members of the public help us fight crime every day and calls and reports to us make such a big difference, as shown by the above examples.
"If you are working at home more or spending more time indoors and you notice something in your community that doesn’t feel quite right, please tell us.
"While some crimes have decreased due to lockdown, we know some of the more serious offences are still taking place, such as modern slavery or domestic abuse. Your reports could even provide the key element in helping us prevent these crimes.
"Lockdown has meant we are all making sacrifices and has shown what we can achieve when we work together. We believe our communities can make a genuine difference and in many cases are already doing so.
"An important thing to mention is that you do not have to be sure a crime is definitely happening but any concerns reported to us, no matter how small, could bring someone to justice and could even save a life."
The campaign comes after a Twitter poll revealed 14% of people said they had reported concerns to police directly as a result of increased time at home.
There are now more ways to contact police than ever before. Suspicions or concerns can be reported via the force’s online web chat function here, via the online reporting forms here, or by calling 101. Always call 999 in an emergency.
