Inspector Chris Barnes said: “Our work to educate people about the current Coronavirus regulations continues on a daily basis but where people choose to blatantly ignore the rules and choose to mix with other households or leave home for a non-essential reason then we will take action.
“It’s important that everyone does their bit to stop the spread of Coronavirus and protect our loved ones and the NHS.
“Whilst most people are abiding by the rules we know that some people think the rules do not apply to them and they can ignore them. Our continued enforcement shows that is not the case.”
