Suffolk: Bridge Posters
Motorists travelling on the main routes through Suffolk are being asked to report any suspicious activity following a series of incidents in which objects have been thrown from road bridges.
Posters have been placed at a number of bridges over the A14 and A12 with the message: Spot Anything Suspicious? Call 999.
The posters also have a bridge reference number, which people can quote to help the police arrive quickly on scene.
They are the latest response by the emergency services, local councils and the Highways Agency who are working together to tackle the issue.
Extra patrols are taking place in areas around bridges on the key routes in the county - and an investigation lead by a detective superintendent has been launched to catch those responsible.
Suffolk's County Policing Commander, Chief Superintendent David Skevington, said:
"Our investigations are continuing into these incidents and motorists using the key route network in Suffolk could provide us with important information.
Hopefully, these signs will prompt motorists who see anything suspicious to get in touch immediately, after finding a safe place to stop and make a call to us.
We are taking these crimes extremely seriously. Fortunately, no one has been injured in these incidents – but it goes without saying that throwing anything from a bridge onto a busy road has the potential to result in road traffic collisions causing serious injury – or even death.”
The signs have been provided by the Highways Agency.
Dave Gingell, Highways Agency Regional Director in the East, said: "Safety on our roads is our top priority and we are doing everything we can to assist Suffolk Police in bringing these dangerous and irresponsible activities to an end.
We would urge members of the public to report any suspicious activities to the Police without delay."
