Whilst we are keeping an open mind, we are very concerned for her and need to know she is safe and well as a matter of urgency.
We are carrying out extensive inquiries to trace Zoya, with specialist officers from across the force working around the clock to try to find her.
We are looking into a number of possibilities around Zoya's disappearance, including her running away from home, her being taken against her will or any worries Zoya may have had herself.
If Zoya hears this appeal herself, I want her to know that she is not in any trouble. We just need to know that she is safe and offer her help.
