Police have urged young people in the city to continue to follow the current Covid guidelines after incidents involving large groups on Parker’s Piece, Midsummer Common and Jesus Green.
As a result, patrols have increased across the city and green spaces to encourage people to follow the rule of six.
Superintendent James Sutherland, area commander for the south of Cambridgeshire, said: “Our message throughout this pandemic remains the same that this is about personal responsibility.
“While the majority of people are acting responsibly, there are a few who are choosing to ignore the guidance and causing disruption for the local community.
“The rules are very clear that no more than six people can be together inside or outside and we urge everyone, for the sake of the health of their families and friends, to continue to follow the law.”
Director of Public Health for Cambridgeshire and Peterborough, Dr Liz Robin added: “We know how much young people have been affected by the Covid-19 pandemic and the national lockdown and that many are concerned by its effect on their education, job prospects and social life, as well as their mental health and well-being."
