Paying the amount of a bounced cheque to avoid consequences

I am Ravi, doing business in Ajman.

I had to come to India on an emergency by Aug 18. Unfortunately, there was a cheque of AED 120K issued to one of the suppliers [in Sharjah] and it got bounced.

I have personally called and informed them, upon reaching back I will give the money.

They are not accepting my request and started threatening my son who's living alone in the UAE.

He's calling me to India saying that they will put me in a UAE jail [in case I am there] and they are going to file a new case in India to stop me from travelling to the UAE.

Now, they're demanding me to pay AED 140K, otherwise, they will not withdraw the case against me.

If I arrange AED 90K now & surrender the passport, will the police allow me to go out to arrange the balance amount?

In case I could arrange the full amount of AED 120K will they release me?

Any possibility to clear it off without arresting me?

If I arrive at Dubai Airport, will I be shifted to Sharjah? Or Ajman?

Please advise how to resolve this.
