Authorities say three girls selling lemonade in central Georgia to raise money for a hospitalized toddler were robbed of about $150 at their stand.

Houston County Sheriff's Lt. Jon Holland said Monday that a man and woman approached the girls Saturday and the man snatched the money jar from a 13-year-old girl.

Authorities told WMAZ-TV that a 21-year-old woman was subsequently arrested and deputies are seeking a male suspect.

The children were trying to raise money for a cousin of one of the girls, a 2-year-old who will soon undergo treatment for an intestinal disease in Cincinnati.

Holland called the robbery "a first" for him in his years of crime-fighting, telling The Associated Press: "I've never had a case where a child at a lemonade stand has been robbed."
