London Tonight reporter Marcus Powell was stopped by police in the City who told him that filming was not allowed.
The incident, yesterday morning, occurred while the crew were attempting to film a piece about Grant Smith who was searched by police after taking pictures for a project on churches 24 hours earlier.
The crew were allowed to continue, but only after Powell showed the police officer his press card.
The drama took place shortly before the ITN crew crossed the river to interview AP's news editor for an item broadcast on More4 News last night.
