Claiming back a security cheque from partner as per agreement

I have issued a cheque as a guarantee to a person who has joined my business as a partner. He did not want to join my license but only a partnership agreement to be signed.

The cheque was issued on an agreement that when the partnership agreement is signed on a later date, he will return the cheque. He did not give my cheque back on the day we signed the partnership agreement.

The business went into a loss and shut down but he is threatening me with the cheque. Can I approach Sharjah police in advance to get my cheque back and avoid police case against me?
