The new emptier that redlinesman has is either a barcrest or a bellfruit, i think that he is on to something brand new.
This trick is about 30 days old.
He was in london around mid december & in brighton late dec, the emptier he was doing came from brighton.
He does have a security team, he only brings one person per time with him on his travels,
If he came with a team then it would be a very expensive day for him.
I will do a bit more resurching & work out his emptier as well. :P
