I am writing in response to the article about the influx of fake £20 notes (Traders warn of £20 notes scam, February 20)

This criminal activity has been going on far too long.

I have links to Streatham and know small businesses who have been affected by this.
This thievery occurs accross the high street, but no police or officials have come forward to warn businesses or people to be vigilant.

My guess is this is a London-wide problem. It is scandalous this kind of organised crime has robbed  people and businesses for so long.
