VEGAN cake mix was mistaken for drugs.

British Transport Police is reminding people to label their food after the blunder today at Gatwick Airport.

The force wrote on twitter: “Huge drugs bust at Gatwick airport. In collaboration with @ukhomeoffice powders tested and discovered to be vegan cake ingredients."

The BTP urged passengers to label foods and to "bring samples of cakes" on their next visit.

A spokesman for the British Transport Police said: “We received a report at 1.34pm.

“Cleaners found a bag contained many bags [of what appeared to be drugs] in the first class compartment of a train.

“Obviously it was tested and found to be fine."
