Parents and children in Rockland are on alert after police say two 10-year-old girls were approached by a strange man. The girls were walking along Pheasant Drive in West Nyack when police say a man pulled up in a car and asked them, "Is this Pheasant Drive?" The girls kept walking and that is when the man allegedly got out of his car and followed the girls asking the same question. The girls ran to a nearby house and police say the stranger took off. Police are hoping a sketch will help lead them to a suspect. Anyone with information is asked to call Clarkstown police at 639-5800.
