Ex additional director harassing us

I appointed my friend Ravi as co founder, CTO and Additional Director of my company. He was working part time with us from March 2021 till October 2021 while being full time employed at another firm. We also allocated him 24% equity to him in the company. There was another co founder who left in September and his shares me and and another co-founder who started the operations divided among ourselves. Ravi tried to force us to allot him additional shares but we did not agree. So Ravi threatened us to leave the company and we told him we are fine with him leaving. He also took with him some parts of our code ( our intellectual property ) and database of our users. We have approached the police for filing an fir against him for his criminal act. Us there any way we can take back the shares ? The shares have not been vested on him and we have signed an Sha according to which he has no right or claim to the shares not vested. We have already issued the share certificate to him. Since leaving he has tried to harm the company in different ways like deleting sections of our website and app, soliciting our employees and harassing our employees and spreading rumours.
