This morning I arrived at Streatham Common station to the sound of an alarm and the platform milling with police officers. As I crossed over to the London platform the siren stopped and it became apparent that the police were simply warning of mobile phone thefts. Not only that but they were marking peoples phones and batteries with postcodes and house numbers to make returning stolen phones to their rightful owners easier.
I of course had mine done and it was a really nice start to the day. Friendly smiling police in the community.
