Airline staff were arrested at London's Heathrow Airport
UK customs officers are questioning the entire crew of a South African flight, after a haul of cannabis and cocaine was found concealed in luggage.
The 15 South African Airways crew, including the pilot, were arrested after their arrival from Johannesburg at Heathrow Airport in London.
Customs officials said the drugs, worth about £310,000 ($425,000), were found in three bags at a clearance point.
Some 50kg (110lb) of cannabis and 4kg (9lb) of cocaine were seized.
Customs officials said the drugs were discovered in luggage as the crew of 10 women and five men passed through customs on Tuesday morning.
Her Majesty's Revenue & Customs spokesman Bob Gaiger said: "Those arrested are now being held in custody and will be interviewed by investigation officers."
Robyn Chalmers, a spokeswoman for the South African government-owned airline whose flight is at the centre of the investigation, said in a statement: "They are being questioned to identify the owner of the bags."
