GREATER Manchester Police (GMP) chiefs have stepped up their campaign to stop motorists using mobile phones while driving.

'Spotters' in unmarked vehicles will be deployed at various times to catch out drivers.

The renewed clampdown comes as latest figures show that 6,502 drivers were issued with fixed penalty notices by GMP last year for using mobiles while driving.

Now, officers are warning drivers who continue to use mobile phones illegally that they will be landed with a fixed penalty notice or face prosecution.

GMP says that research shows drivers are four times more likely to have an accident if they use a mobile phone while driving because of the adverse effect on concentration and anticipation. Hands-free calls are also distracting and drivers should be aware they risk prosecution for careless or dangerous driving or failing to have proper control of their vehicle if using a mobile phone.

GMP's road safety officer, Inspector Brian Wood, said: "When the offence of using a hand held mobile phone came into force, most drivers heeded the warning. This operation is targeted at those who still disregard the message and put other people in danger as a result.

"We will be watching for drivers using mobile phones illegally and take the appropriate action."
