More than 100 inmates are believed have escaped a prison on the British Virgin Islands after the building was blown open by Hurricane Irma.

As many as 120 prisoners may have fled the 'partially destroyed' site on the island of Tortola as the storm wreaked another day of devastation on the Caribbean, sources told Sky News.

One British Virgin Islands resident, Paul Exner, who is president of expedition firm Modern Geographic Sailing, said that the inmates were initially kept back by armed guard but were 'let go'.

Mr Exner explained that there is 'total devastation all around,' adding: 'No infrastructure at all. Island will need food and water soon. We can live in our house for another two weeks as a family.

'We are gathering spare plywood and and materials to rebuild. No power to house. Hand tools only.

'Tomorrow we deal with hurricane Jose 90 miles to our north.'
