BOBIGNY, France (AFP) - A Paris suburb has come up with an innovative plan to fight a plague of dog droppings on local streets - catching offenders on closed-circuit television cameras.

The commuter town of Montereau-Fault-Yonne south-east of Paris said on Monday that municipal police would begin using a decade-old network of CCTV cameras to track down dog owners who don't pick up their pets' droppings.

"This will allow us to identify and seek out pet owners with no sense of civic duty and, in the event of repeat offences, to fine them" 35 euros (S$59), town mayor Yves Jego told AFP.

"I would not have installed cameras for this," he said, but "we have an existing network that we can use for other services".

He said using the cameras against irresponsible dog owners was no different from filming traffic offenders and was not an invasion of privacy because "we are not filming people at home".
