ANTI-SPEED CAMERA protesters on the M4 motorway caused two cars to crash into each other last Saturday, Wiltshire police said this week.
The protesters were part of a convoy travelling between 25mph and 56mph on a stretch of motorway near Swindon, causing traffic to bunch up.
'The accident was caused by the artifi cial build up of traffic - we told protesters that this would happen.
'Fortunately no one was seriously hurt this time, ' said Wiltshire Police inspector Wayne Smith.
The protest was organised by M4Protest, which opposes speed cameras on motorways (News last week).
Traffi congestion built up for two hours on Saturday morning between Junctions 14 and 18. Up to 5,000 cars were expected, but the police said only 200 took part.
Protesters were supposed to travel at 90km/h, but some cars travelled at just 40km/h. Smith admitted that he would consider very carefully whether a repeat event should be allowed to take place.
