Police have confirmed the protest march halted in Bushey Heath last week had "no evidence of race-related criminal offences".
Hertsmere Chief Inspector Dean Patient said: "We appreciate the sensitivities within the community on this matter and we have investigated it fully but no evidence of race-related criminal offences was found.
"The possession of a national flag on its own does not constitute an offence and the constabulary is also mindful of having to balance residents’ rights to feel safe with the others’ right to freedom of expression.
"The Bushey and Radlett Safer Neighbourhood Team continue to monitor the situation and are liaising with the local community in order to provide reassurance.
"If anyone has concerns then they are urged to contact Sgt Noel Buckley on 01707 806645."
