A scheme to combat thefts of batteries could help livestock farmers in south Norfolk.

Thefts of batteries used to power electric fences have more than doubled across the district in the past year, according to Norfolk police.

Last year, more than 24 batteries, typically worth more than �100 each, were stolen – an increase from 10 in the previous year.

The police and South Norfolk Council have joined forces to security mark batteries.

Insp James Brown said: 'It is fair to say the high value of scrap and the fact many of the batteries are kept in isolated locations makes them an attractive option for thieves. 'This marking project will make it increasingly difficult for the batteries to be stolen and disposed of in the counties and surrounding counties scrap sites.'

If anyone witnesses suspicious activity at isolated sites, contact Norfolk police on the non-emergency number 101. If a crime is in progress, dial 999.

To take part in the battery marketing scheme, contact Poringland Police Station by calling 101 between 10am and 2pm Monday to Friday or alternatively email sntporingland@norfolk.pnn.police.uk.
