A total of four people have been arrested after new quarantine rules were brought in for returning residents last month.

Following changes to border restrictions on July 20, police have dealt with 10 individuals who have failed to self-isolate.

They have issued warnings to six and arrested four people, one of whom has been sentenced to six weeks in prison.

According to government figures, between July 20 and August 12, 2,559 individuals returned to the island, which amounts to around 600 residents every week.

Under level four of the island’s border policy, each person returning receives a ’direction notice’ which instructs them to self-isolate.During the 14-day period of isolation, checks are made either by phone or by ’unscheduled visits’ from authorised officers to ensure rules are being obeyed. Any person found breaking self-isolation who is reported to police, could face a maximum penalty of three months in prison or a £10,000 fine.
