WAUKEGAN, Ill. (AP) — Police say a suburban Chicago couple face charges that they kept their 10-year-old daughter in their basement for several months because they believed she was possessed by a demon.

Waukegan police say the 48- and 49-year-old parents were arrested Tuesday on felony counts of child endangerment and unlawful restraint.

The department says an anonymous caller reported someone being held captive. Investigators determined that since at least January the girl had been locked in the basement at night and had limited access to the outside. Police say she was given a training toilet and showered from a bucket.

Child welfare authorities took the girl and her siblings — ages 15, 13 and 7 — into protective custody.

The parents remained jailed Thursday and Lake County court records didn’t list defense attorneys.
