Norfolk Constabulary says it has no record of police helicopter being used in search of missing person.
Mystery surrounds the huge police presence in Cromer at the weekend.
There were dramatic scenes as up to 10 police vehicles, both marked and unmarked cars and vans, joined a Coastguard truck in the seaside resort on Sunday around 1.30pm.
They gathered in the private car park next to the town's Cliftonville Hotel and were supported by a helicopter flying overhead.
A police sergeant at the scene said they were searching for a missing man as part of a county-wide operation.
However, Norfolk Constabulary's press office has today (Monday), said they were unaware of any incidents involving the police helicopter that afternoon.
A spokesperson for the force said: 'Couldn't find any CADs (computer record) of missing people where NPAS (The National Police Air Service) were called.'
But he added: 'There was a search for a missing woman yesterday evening in Cromer. We wouldn't release any more details of the woman as she was found.'
