Coffs-Clarence police ay there is no need for public concerned about a recent spate of alleged thefts from within the Coffs Harbour Police Station.

A male cleaner has been charged with stealing less than $2000 in cash from a drinks fridge inside the station on a number of occasions in January, 2014.

Crime Manager, Detective Inspector Darren Jamieson, said it does not indicate there are potential security problems.

He said sensitive material like crime scene reports and evidence, are properly secured.

"They're all very well secured, nothing's lying around a police station for people to just pick up and read, so there's no concerns there," he said.

"But opportunistic crime does exist, whether it be inside a police station or elsewhere in the community, and at least as police we can take action and put these people before the courts."

Detective Inspector Jamieson said all police staff are screened but that does not provide complete protection.

"They do go through some screening, but obviously there are people who take the opportunity to commit a crime they may not have committed before, he said.

"We just need to be vigilant, in the community or running businesses.

"Just be mindful of cash being left around, and have systems in place like we have at the Police Station with CCTV footage, not just to deter but if somebody does steal something, so they can be caught."
