Police are on the lookout for a well-dressed sexual predator who has attacked two young girls in New York City.

Police say the man, dressed in a suit and tie, attacked a 15-year-old girl in the Chelsea section of Manhattan last week and a 12-year-old girl in Tribeca in November.

In the latest incident, police say the man followed the girl into her building, dragged her into a stairway and forced her to fondle him before fleeing.
