HM Customs and Excise dog handler Rob Pike and his dog Jess check passengers for large amounts of cash at London's King's Cross railway station as part of Operation Payback. Customs and Excise and police want to seize the proceeds of criminal activity being brought into London for laundering from other parts of the UK. As part of the initiative, dogs trained to detect the ink on currency notes will be used on trains and platforms to detect large amounts of cash concealed either on passengers or in their bags.
