WEWS-TV reports that when that child’s mother came to pick up her son, staffers at the Fatima Family Center knew something was wrong. By that time, the grandfather was on his way back with the boy.

The day care is operated by Catholic Charities Community Services. Executive Director Bernadette Washington released a statement saying her organization would review its procedures and make sure the staff understands how to release a child to the proper person.

Washington also told WJW-TV the two children on Thursday were safe with their right relatives within a half-hour of the mix-up.

No charges have been filed.
