"The government committee against racism and anti-Semitism will send a delegation to Beziers. It will assess the situation and decide whether those facts provoke or not discrimination and racism," the prosecutor office said in a statement cited by Infos-H24 news website.
The banner campaign was initiated by the town’s authorities, led by far-right mayor Robert Menard, who is close to the National Front nationalist movement.
"They have arrived. Migrants are in the center of our town," one can read on posters across Beziers.

Beziers is a small town in southern France with a population nearly 73,000. The French government plans to build a center for migrants in the town.
Menard has opposed the construction of the new migrant center in his town.
"They are doing this while the local authorities have been working for two years to renovate the city center. This will be a serious problem for the region," the mayor said last week.
When the government plan was announced in September, the populist mayor said he did not want his town to be turned into a "small Calais."
In an interview with Sputnik, he blamed the French government for its inability to resolve migration-related problems.
"So the government offers to 'distribute' the problem throughout France, but I do not want to grapple with this problem because I have already enough migrants [and don't need] to take in more of them. Earlier I opposed the arrival of Syrian 'refugees' in Beziers, and now I do not want Calais migrants to come to my city which is poor enough and which has other problems to deal with," he said.
