I think I saw them this evening, around 7pm, cycling up Bermondsey Street near the florist (Iglu?).
I was on the pavement looking at properties in the window of the estate agents and one boy cycled between the window and where I was standing on the pavement.
The other 2/3 cycled very fast on the street towards Tooley Street
I was approached on Great Dover Street early Monday morning by someone asking me where number 2 GD Street was, I was not sure but told him he was on the right street but should walk towards Boro HI St as he was closer to that side. He asked if I can check on my smart phone... Told him I did not have one (lied) he then did a huge tut before walking off!!
I got done last night. On Jamaica road walking from Bermondsey Tube Station to Abbey Street, guy on a bike, dressed in all black, black puffer jacket, riding a BMX. Brushed past me and grabbed it out of my overly inviting texting paw. Stupid of me, I know. Don't let this happen to you, keep your phones out of sight.
