The £2 million police review of the Madeleine McCann case will examine calls from psychics which were previously ignored.
Detectives are studying around 100 logs of calls that were discounted because the callers said they were psychics or had dreamt about the high-profile investigation.
Critics said the decision to include information from 'supernatural' sources was a waste of resources.
Police were inundated with calls about Madeleine after she disappeared during a family holiday in Portugal on May 3, 2007.
Crimestoppers set up an international number and sent the information they received to Leicestershire Police, the McCann family's home force, and to Portuguese police.
But Leicestershire Police reportedly asked Crimestoppers not to forward information from psychics, or calls based on dreams about the case. Some 100 call logs were not passed on because of the request, Sky News reported. But they have now been sent to the Scotland Yard team reviewing the case.
The information will be examined and entered into the police computer for the first time to ensure no detail has been missed.
