Hello dear apple team

I have a problem and wish what u can help with with a solution

i had iPad and iPhone with the same iCloud

to be honest I don’t know how to proper Use iCloud

so someone stole my iPad and iCloud was there with my pictures , but my problem is what person who stole my device is sending my private pictures to the people

I would like to know if it’s possible to delete all the pic tired from the iPad which somebody stole from me , I’m a public person and it’s a scandal for me

I already removed iPad from the settings But want to remove my private pictures as well
