The backlash against speed cameras is growing and it won't be long before someone gets hurt. Detectives in Northamptonshire are investigating an explosion by a speed camera on the A605 at Thrapston. The camera was destroyed and metal fragments were found fifty feet away. Whilst many cameras in Northamptonshire have been vandalised or driven into, this is the first one to be blown up. Detective Constable Alison Farr, of Kettering CID, said on Tuesday night: "We are treating this crime extremely seriously, it was an unbelievably irresponsible act. The incident occurred in the early hours of Sunday morning. "The force of the explosion forced metal right across the road and had someone been driving past at this time, the occupants would have been seriously injured or killed." The electronic parts of the £25,000 camera were left hanging out after the attack, which took place between midnight on Friday and 10.30pm on Saturday. Experts from the Army's explosive ordnance disposal team have examined the scene and taken items for further examination. In recent months cameras nationwide have been vandalised in spectacular fashion, including the 'necklace' tactic where a tyre is placed over the device and it is set alight. Det Con Farr said: "Officers are looking into whether or not the incident is linked to similar attacks across the country."
