QUEENS - A woman in Queens kept two South Korean children as slaves in her homes for six years, according to police. 

Officials say Sook Yeong Park took the brother and sister, who are now 14 and 16, into her home in 2010, and allegedly seized their passports. 

According to investigators, the kids were forced to give her back massages, do household chores, work in a store and hand over all of their earnings.

Police say the abuse came to light when a high school assistant principal noticed bruises on the girl's legs.
