The increasing number of attacks on cash machines in Northern Ireland has prompted operator LINK to offer a reward of up to £25,000 to anyone who can help catch those responsible.
Since March there have been 13 thefts of ATMs across Northern Ireland with the cash machines physically removed.
Graham Mott, senior LINK spokesman, said: "We're urging the public to pass on information with any information that they may have about cash machine crime, for example card skimming or physical attacks on cash machines themselves.
"Even something that may sound insignificant could be part of a bigger picture and prove invaluable in convicting someone involved in cash machine crime."
Some of the thefts have involved the use of diggers or other heavy machinery.
There were three such raids in different parts of Northern Ireland in just four days in October. That compares to only two ATM attacks in the whole of 2007.
Link has joined the Crimestoppers charity to combat the crime across the UK.
A PSNI spokesman said the force had a close relationship with the banks.
"Police would also advise owners of large plant machinery to ensure they are locked and secure at all times," a spokesman said.
"Opportunist thieves will steal insecure plant machinery for use in crimes such as ATM thefts."
