The four South Africans plus three Britons were charged in the
Coventry Magistrates Court on 2 April 1984 with conspiring to export to South Africa high pressure
gas cylinders,
radar magnetrons, aircraft parts and other military equipment in violation of the mandatory
arms embargo imposed by
United Nations Security Council Resolution 418. The uncovering of their smuggling operation and subsequent arrest followed the discovery of a shipment of
artillery elevating gears at
Birmingham Airport in 1984. The Coventry Four were
Hendrik Jacobus Botha,
Stephanus Johannes de Jager,
William Randolph Metelerkamp and
Jacobus la Grange. In the
front company (McNay Pty Ltd) they operated on behalf of
Kentron, Metelerkamp was the
Managing Director, Botha was in charge of administration and security, De Jager was the company accountant, while la Grange was the technical expert. The Coventry Four were remanded in custody and their passports confiscated. After several weeks, they were released on bail of £200,000 when
André Pelser,
1st Secretary at the
South African Embassy in London (
South Africa House), waived his
diplomatic immunity and stood
surety. Then, following an alleged intervention from the
prime minister's office, they applied to a Judge sitting in
Chambers to recover their passports. In May 1984, Judge Leonard granted the request and allowed the Coventry Four to travel to South Africa, on condition that they undertook to return to Britain for their trial. Salt was given a 10-month jail sentence and fined £25,000 for his part in the operation, while the UK companies involved paid fines of £193,000. ==Controversial visit==
