PHILADELPHIA — Philadelphia’s police commissioner credits an abducted woman’s fighting spirit with helping to save her life.

Charles Ramsey told ABC’s “Good Morning America” on Thursday that Carlesha Freeland-Gaither kept struggling with her captor despite being bound.

Ramsey said today the 22-year-old nursing assistant’s resistance, “probably helped keep her alive.”

He said Freeland-Gaither is resting at home in Philadelphia after law enforcement agents rescued her Wednesday outside Baltimore and arrested suspect Delvin Barnes.

He said detectives are giving her time to settle down before completing interviews.

Police said Freeland-Gaither, who disappeared Sunday night, had some injuries but was generally doing OK.

Barnes is being held on an unrelated Virginia warrant alleging attempted murder, assault and malicious injury with acid, explosives or fire
