Knowing the whereabouts of a person in Dubai after being contacted by police

My mum was accused of stealing jewelry from her former employer, and her employer reported it to the police which she worked for 6 years as a nanny.

She was called by a police officer telling her to come to the police station and she went there. Since then, I cannot reach her through the phone.

I'm afraid she's been detained. Please enlighten me. I need answers I'm worried about my mum.

I'm in the Philippines and my mum has been working in Dubai for almost 8 years now.
