Hi Linda,
If you suspect intimidation then a criminal offence may have been committed and should be reported to the police without delay. You should also raise it with your community safety or crime prevention teams and possibly adult social care if there are elderly and possibly vulnerable people at risk, and find out and follow your council's safeguarding protocols.
I would also have thought you wouldn't want to take the application to committee until such time as these issues had been resolved, and in the meantime to seek legal guidance on whether such behaviour has any implication either on the outcome of an application or how it should be processed.
