West Midlands Police have seized over £70,000 in cash at Birmingham Airport during a week of action to deter criminal activity.
The police says it was seized from individuals travelling abroad - in one instance, £30,000 was found stuffed in nappies.
They say the cash may be the proceeds of crime or destined to support terrorism abroad. The investigations are on-going.
Police says it was looking at a range of issues at the airport - from general crime and pickpocketing to looking out for people possibly being coerced into travelling.
Tackling terrorism also remains important.
