Police investigating allegations of vandalism linked to a row involving the Broads Authority (BA) are hunting for two suspects.
The organisation contacted Norfolk Constabulary after some of its riverside mooring signs were emblazoned with stickers calling for the resignation of its chief executive, John Packman.
He is the focus of a growing mutiny by boaters angered at a recent 13pc increase in boating tolls and the way the Authority is run.
The BA says the stickers - which say "Packman Must Go" - are a form of bullying.
It has passed police CCTV footage which shows two people putting the stickers on one of the signs, as well as the car they arrived in.
The stickers - which have since been removed - have appeared at at least two riverside locations in recent days, at Ranworth and Reedham.
The incidents, and the row over tolls, are the outbreak in a long-running conflict between different factions on the waterways and at the Authority itself, dubbed 'navvies' and 'parkies'.
The 'navvies' are those concerned primarily with navigation and boating, while the 'parkies' are accused of being more focused on fulfilling the Authority's National Park obligations.
Norfolk Police confirmed two reports of criminal damage have been made to them after stickers were placed on signs on March 31. The investigation is currently ongoing.

A Broads Authority spokesman said: “The Broads Authority will not tolerate any form of bullying or harassment of its employees, volunteers or members.
"Matters of anti-social behaviour or vandalism will also be treated appropriately.
“CCTV cameras have provided clear images of two people applying stickers to Authority property along with their car registration number.
"This evidence has been presented to the police who are taking the matter seriously and will decide what action is appropriate.”
He said the signs carry “vitally important” safety information while defacing the signs is irresponsible and would divert BA and police resources.
He added: “We would urge those involved to raise their issues directly with the Authority.”
The vandalism has not been welcomed by Broads Reform Action Group (BRAG) members – a navvie group demanding changes at the authority – with one saying they could not condone defacing public property.
