BT is stepping up attempts to combat broadband cable theft, which continues to cause customer service problems for consumers and businesses across the UK.
The high value of copper has made internet cabling a precious commodity for criminals in recent years, meaning ADSL broadband networks are under continued attack.
Following a spate of thefts in South and East Yorkshire, BT is now offering a £2,000 reward to anyone who provides information leading to a conviction for cable theft.
The broadband provider has teamed up with national charity Crimestoppers to reduce the number of incidents in Hull and Doncaster, where particularly high levels of criminal activity have been witnessed during 2011.
Bernie Auguste, Head of Security for BT Openreach, said the firm was working "very hard" to prevent further attacks on its copper infrastructure, and get those affected by cable theft re-connected to the internet as soon as possible.
"By working closely with the police, installing extra protection and increasing vigilance in the area we are reducing the number of successful attacks," she stated.
"However, we really need the public's help in identifying the perpetrators of this crime."
Ms Auguste said members of the public should be on the lookout for unmarked vehicles and individuals who appear to be working on or near man hole covers or telephone poles, particularly at irregular hours.
