A US woman accused of spraying sheriff's deputies with breast milk has been sentenced to two years of probation.

Stephanie Robinette, 37, of Westerville, Ohio, pleaded guilty last month to charges of assault and obstruction of official business.

She was sentenced in Delaware Municipal Court and ordered to pay $US200 in fines on top of court costs.

Robinette was arrested June 25 by deputies responding to a domestic dispute.

Sheriff's officials in central Ohio's Delaware County say she wouldn't cooperate when deputies tried to remove her from a car. They say she told them she was a breastfeeding mother and then exposed part of her chest, spraying them with milk.

A message left with Robinette's attorney wasn't returned. He had previously said his client was embarrassed and humiliated.
