i have not given consent for someone to post a picture of my child and they refuse to remove it also BOYFRIENDS GONE MISSING ON HOLIDAY

My partners family havent seen my daughter since she was a month old because they simply dont care, theyve started takin pictures and posting them of her acting like happy families, they dont even know if shes okay! Ive asked them to remove the pictures and they refuse! It sounds pathetic but they dont even act like aunt and a nan to her so arguing that point is ridiculous! Can i go to the police as theyve refused to take it down and they dont have my consent????
