British customs officials say a South African Airways crew arrested after drugs were found in bags at Heathrow Airport have been released on bail.

HM Revenue and Customs said Wednesday that three pilots and 12 flight attendants on the flight from Johannesburg to London were questioned overnight and have been released on unconditional bail pending further inquiries. They were told to report to a police station in March.

The crew were arrested as they passed through customs Tuesday after officials found 110 pounds of cannabis in three bags. One of the bags also contained around eight pounds of cocaine, worth around $222,000.

The airline confirmed the crew members had been released and said they were cooperating with authorities.
