Security video showed nothing amiss when Frankea Dabbs — wearing dark glasses, pushing a baby stroller and pulling a rolling suitcase — entered a busy Manhattan subway station Monday night.

But after riding uptown to another stop, police say Dabbs purposely left her most precious possession behind on the subway platform: her baby girl. Dabbs, 20, who has a record of petty crimes in North Carolina, was arrested near Central Park on abandonment charges Tuesday after someone recognized her from the video released by police. The name of her attorney wasn’t immediately available.

In a preliminary interview with detectives, Dabbs described herself as a homeless widow from North Carolina who had arrived in New York on July 2, said Stephen Davis, spokesman for the New York Police Department
