The four kilos of cocaine were discovered when officers searched the baggage off a flight from Bridgetown, Barbados, on Tuesday 9 March.
Nick Crouch, Assistant Director of UK Border Agency at Gatwick said:
“This was a good find by UK Border Agency officers which relied upon their vigilance.
“It is especially encouraging as it demonstrates that the strike by the PCS union has not caused the level of disruption intended to our round the clock protection of the border to protect the UK from harm.”
A 40-year-old woman from London has been charged with the illegal importation of a controlled drug.
The UK Border Agency was launched on 3 April 2008, bringing in a single force to protect our borders, control migration for the benefit of the country, prevent border tax fraud, smuggling and immigration crime and make quick and fair decisions on asylum claims.
