Cancellation of an employee from immigration while he's in detention

Hi

My employee is in the central jail in a case, and I cancelled his labour contract but not immigration, but in the labour contract cancellation application written a note to cancel the visa from immigration in 30 days.

My employee in the police custody I don't know when the police will release him. Now, what shall I do if I do not cancel his visa because I only cancelled his labour card for the WPS cancelation?

Give me some advice.
