Crash on Effingham Road this pm

Hi all, 

Can anyone help me? 

A blue Mercedes crashed into the open door of my black Lexus while I was putting my daughter in her car seat at about 3pm this afternoon on Effingham Road . Insurance company are asking if there were any witnesses as they want my version of events colloborated. There were a few drivers behind the Merc, were any of them you or did anyone mention this to you? I don’t think there’s cctv on the street so it would be amazing to find one of these people to help prove it wasn’t my fault. 

Does anyone know how you can find out if there is CCTV on your street? I don't see any cameras/ domes so I'm assuming no. 

Thank you!
