"We are reminding the public to adhere to the Health Protection (Coronavirus) Regulations, which include restrictions on movement that stipulate that no person may leave or remain away from the place where they normally live without reasonable excuse.
"While we will have additional officers on patrol, in and around the North Coast this weekend, we are reminding the public of the need to maintain safe social distance and to stay within their bubbles.
“To be clear, people who are showing disregard should expect swift enforcement. We will always engage with people first explaining the guidance and the law and encourage people to comply, judging each case on its own merits. However, where we are left with no choice but to enforce, we will take this measure in order to protect the most vulnerable members of our communities and help protect our NHS.
