An election candidate hoping to win the Gedling seat in Nottinghamshire has been spoken to by police about his behaviour to shopkeepers in Mapperley.
Conservative candidate Bruce Laughton was allegedly confrontational with traders who exhibited posters opposing car parking charges.
Mr Laughton said he apologised if he had upset anyone but was "just campaigning on their behalf".
Police said they spoke to Mr Laughton but he had not committed any offence.
This incident received considerable publicity on the East Midlands regional television news yesterday evening.
