Anger over her boyfriend's seeing someone else apparently prompted a North Philadelphia woman to run down three members of a family, including a 5-year-old girl, in the Fairhill section Tuesday night, police said yesterday.

The 33-year-old woman who was the target of the suspect's rage remained in critical condition with head and body trauma at Temple University Hospital, said Officer Elizabeth DiDonato, a police spokeswoman.

The girl, who suffered a broken hip and leg, was in stable condition at Temple University Children's Medical Center. Her 47-year-old grandmother, sister of the younger woman, also was reported in stable condition, with a broken leg.

Police did not release the victims' names.

Police arrested Wykia Townsend, 22, of the 3100 block of North Bancroft Street, and charged her with three counts each of simple assault, aggravated assault and recklessly endangering another person.

Sgt. Leo Costello of East Detectives said jealousy was the motive.

According to police, Townsend argued with the 33-year-old woman on the 2800 block of Germantown Avenue, then jumped into a Nissan Maxima before driving at the three victims Tuesday night.

She fled but was arrested nearby, at 12th Street and Glenwood Avenue, police said.
