How to get the pending labor dues after being deported from the UAE?

Hi,

A friend of mine got deported recently. He has his end of service and salary pending to be received. The employer is not responding as they think that the deported employee won't be able to claim his dues back.

When a relative approached the employer, they said they are not able to release the payment due to financial constraints which were hard to believe as all the employees were paid on time.

Please advise if there are any legal measures to be taken so that the deported employee gets his pending dues.

Regards,
