March 17th, 2007 - The dirty duo - believed to be a husband and wife aged around SEVENTY - offer to help clean up their victims before snatching their cash.
Albert and Doreen Croucher lost £4,000 as they left a bank after making a withdrawal at Eastbourne, East Sussex, last month.
Mr Croucher, 58, said: "I felt this blast from the buildings above us. The smell was instant and vile.
"Just then a lady came over with tissues and helped clean it off. It was only later that I realised she had fleeced me."
The theft is the third in a few weeks in Sussex.
Other attacks in Brighton have netted £11,500.
A police spokeswoman said: "This is a such a shitty crime."
Just kidding, the police spokeswoman actually said: "This is a totally repulsive crime." But it would have been funnier the other way.
