(AP) A nurse who promised to defy Maine's quarantine for health care workers who've treated Ebola patients has followed through on her vow.



Kaci Hickox left her Fort Kent home with her boyfriend on Thursday and went for a bike ride, trailed by reporters and a state police cruiser. They returned about an hour later.



State officials are going to court to keep Hickox in quarantine for the remainder of the 21-day incubation period for Ebola that ends on Nov. 10.



Police are monitoring her, but can't detain her without a court order signed by a judge.



Hickox contends there's no need for quarantine because she's showing no symptoms after treating Ebola patients in West Africa. She told reporters on the bike ride that she hopes that a compromise can be reached "amicably."
