Incorrect handling of digital forensic evidence could affect the outcome of a successful investigation and prosecution. Follow these simple steps before contacting the NHSCFA Forensic Computing Unit.
STOP! Don't touch
Never attempt to corroborate the accusation by having 'a quick look'. This may jeopardise the evidence and possibly rule it inadmissible in formal proceedings.
Remember that computers and other electronic devices record everything, including who logged on and when. If the subject can show that their computer was accessed at a time when they were not present, they may claim that evidence found therein was put there by someone else.
Time is of the essence when it comes to digital evidence. Get advice as soon as you become aware of the situation. The Forensic Computing Unit (FCU) can advise you on what your next steps should be.
Contact the FCU straight away! Besides NHS Counter Fraud Authority's own investigations, the FCU can provide forensic computing and other services for any NHS investigation carried out by an authorised person.
