Officials on the Isle of Man have introduced a three-week circuit breaker lockdown following a rise in coronavirus cases after a ferry crew member tested positive.
Masks and social distancing measures were also removed as the island attempted to get back to normal.
However, on Tuesday chief minister Howard Quayle announced a new lockdown of 21 days as a result of “transmission in our community that we cannot see and that we do not understand”.
He said: “After lengthy discussions that weighed heavily on our minds, we have decided that we cannot allow anything to put this longer term exit at risk.
“We need to intervene now. If we do so now, and if everyone does their bit, we will again stamp out the current outbreak that seems to be moving under the surface of our community.”

The island currently has 58 cases of coronavirus, three of which have no immediate link to identified clusters of the virus.
On 18 February, Quayle announced there were COVID cases on the Isle of Man that were not among people who had travelled there and entered self-isolation.
They were linked back to a member of staff working for the Isle of Man Steam Packet Company, which runs ferries to and from Liverpool, Belfast, Dublin, and Heysham in Lancashire.
At the time, the company said the crew member, who was not in a passenger-facing role, had a test while off-duty and was placed in immediate isolation, with contact-tracing underway.
Under the new measures, which came into force just after midnight on Wednesday, schools and businesses will close and residents are urged to stay at home.
Quayle said the island’s vaccination programme was on track to deliver first doses to all over-50s and clinically vulnerable adults during April.
Before the new outbreak, a total of 484 people on the Isle of Man had tested positive for coronavirus since the start of the pandemic, with 25 deaths recorded.
