Robert Yachen Lee, Yoghurt store owner 'kidnapped worker and locked her in a box

The owner of a frozen yoghurt shop has been accused of attacking an employee, removing her clothes, binding her with tape and locking her in a box.

Robert Yachen Lee is being held on $10m bail charged with kidnapping to commit rape and first degree murder.

Prosecutors say Lee lured a female employee into a soundproof upstairs storage room above his O My Yogurt store in Monterey Park, Los Angeles County and knocked her out.

While she was blacked out he then allegedly removed her clothing, bound her with tape and put a collar around her neck.

When she woke the terrified woman was naked, except for an adult diaper. She was bound with tape, and lying face down in a box.

Authorities said the woman was put into what appeared to be a soundproofed box and placed into recently padded and soundproofed room that was part of the storage suite.

The woman managed to escape fleeing to a nearby optometrist's office where she asked them to call the police.

Lee was arrested the same day.
