If you would like to report dangerous behavior perpetrated against cyclists (or pedestrians) during Critical Masses, or on London's roads in general, please email the London Transport Action Group [londontransportactiongroup@googlemail.com] with the following information:

1. Date and Time of Incident

2. Description of the Vehicle: Number Plate, Car/ Motorbike Type, Colour, etc

3. Brief Description of Incident

4. Your Details [optional]

These details will be stored on a Database with LTAG, and we aim to build a body of evidence against dangerous motorists. Eventually this Database may go public (minus your details), in order to identify those who put our lives at risk every day. Your Details will never be passed on to Third Parties, the Authorities or anyone else; if a case would benefit from the information, we will seek your express permission before passing anything on.
