The joint anglo-dutch raid
On land, the UK Thatcher government sharpened the 1967 anti-offshore broadcasting law further, to time to permit the boarding and silencing of stations operating even in international waters, if British nationals were involved. On August 19th 1989 officials from the Department of Trade and Industry and their counterparts from the Netherlands Radio Regulatory Authority carried out a raid on the Ross Revenge, in which vital equipment was wrecked or confiscated. Part of the raid was broadcast live before officials finally cut off the transmitters. Although the british staff were not arrested and were left on the ship, Radio Caroline was no longer in a position to broadcast.
A few months later following the police raid, a low power Radio Caroline service restarted from the Ross Revenge. This survived until November 1990 when lack of fuel and supplies finally put the station off the air. Most of the previous broadcasting staff had by now left. A skeleton staff of volunteers remained onboard for a year as caretakers, whilst fresh funding and equipment was supposedly being gathered on land.
In November 1991 hurricane force storms caused the ship to break anchor and drift onto the Goodwin Sandbank in the North Sea. the crew were rescued by RAF helicopter. The Ross Revenge was later salvaged and brought into harbour in southern England.
