PARIS — A 2-month-old Roma infant was buried on Monday in a town south of Paris amid accusations that the mayor of the nearby town where the baby died had refused burial space in the local cemetery. The episode has prompted antidiscrimination investigations by local prosecutors and France’s human rights ombudsman.

The Roma community in France has been under pressure from the government as the authorities and the police accelerate a policy of dismantling encampments across the country. In 2013, the deportation of a Roma teenager, Leonarda Dibrani, created such a furor that President François Hollande intervened. He agreed to allow Ms. Dibrani, but not her family, to return to France. She refused the offer. Other Roma have been attacked near encampments. Last June, a 17-year-old Roma boy was beaten unconscious by a gang of young men in a Paris suburb.

The baby, who was buried Monday and who was identified by the French news media as a girl, died of sudden infant death syndrome between Dec. 25 and 26 in a shantytown near Champlan, about 10 miles southwest of Paris, according to an association that defends the rights of Roma in the region. The association accused the town’s rightist mayor, Christian Leclerc, of refusing to grant a burial space in the municipal cemetery for the infant.

Mr. Leclerc, who is not affiliated with a political party, denied refusing to grant the space and said the dispute was a result of the news media’s mischaracterizing his statements and an administrative bungling of the Roma family’s burial request while he was on leave from town hall.
