The posters, like this advert, were in Polish and English
A public meeting called to allow Polish residents to report antisocial behaviour against them ended with none attending.
Police said this suggested the Polish community of Corwen, Denbighshire, had "no real concerns".
Posters had gone up around the town, and in local factories to inform the community that support was available.
North Wales Police community officer Pc Keith Sinclair said: "They obviously don't feel the need to come here."
Pc Sinclair was at the town hall to address concerns at the meeting, scheduled ahead of a planned meeting of the town council.
At a similar event last year it emerged that some Poles had been victims of antisocial behaviour by local residents.
As a result of the 2008 meeting one local person was served with an £80 fixed penalty for harassment.
Incidents reported at the time included verbal abuse as well as banging on doors and windows of households.
Police said they were unaware of subsequent problems but wanted the Polish community to know their support was continuing.
Councillors had been ready to take questions from Polish nationals but, after a 15-minute wait, no-one had come forward and they had continued with the rest of the agenda.
Pc Sinclair, North Wales Police community beat manager for minority communities, said: "Whilst it's disappointing nobody turned up, it's reassuring to know they haven't got any real concerns.
"They obviously don't feel the need to come here, because they now have regular direct contact with myself."
Police had planned to distribute a questionnaire to members of the Polish community.
It included questions such as "Do you feel safe in your community?," "How satisfied are you with Corwen police?" and "Have you had any dealings with the police?".
