ORLANDO, Fla. (AP) - Authorities have taken custody of five Orlando children whose mother allegedly left them home alone while she spent the night partying.

A judge determined the children couldn't remain with 29-year-old Formeka Sanders or Sanders' mother, who has a history of drug use.

Sanders was arrested on child neglect charges early Monday morning after a security guard found her 4-year-old wandering a parking lot. The boy said he was alone and led the guard to an apartment where four siblings ranging in age from 2 to 12 years were sleeping.

Responding officers tried to call Sanders several times, but say they could only hear loud music when she picked up.

Investigators say Sanders told them she believed the 12-year-old was responsible enough to care for his siblings.
