Police have arrested the parents of an 8-year-old Liberian girl who was allegedly kidnapped and raped by four boys on felony child abuse charges.

Child neglect reports were filed against the girl's 59-year-old father and 47-year-old mother on two separate occasions, MyFoxPhoenix.com has reported. The parents each face eight counts for a series of abuse and neglect incidents dating back to 2005.

A Phoenix police spokesman says the parents were arrested Friday without incident.

The parents are not being named to avoid identifying their daughter, who police say is a rape victim.

In an investigation conducted over the past several months, detectives learned that Phoenix Police, Glendale Police and Child Protective Services had been called to the victim's home on numerous occasions dating back to 2005, MyFoxPhoenix.com reports.

Police submitted their investigation of the parents to the Maricopa County Attorney's Office in August. Arrest warrants were issued earlier Friday.

Police say the girl was gang-raped in July by four Liberian boys who lured her to a storage shed with the promise of chewing gum. All four suspects were arrested and charged in the attack.

The girl has since been removed from the home and is in custody of Child Protective Services, MyFoxPhoenix.com reports.
