Removal of a tiktok page?

Is there any way to get in touch with someone through TikTok? There is someone who is getting dth threats from a man who has a severe mental illness.
The man that has received these threats has already contacted the local police and it is being investigated.
This could sound petty to many but it’s really not. You don’t know who is behind a screen and also what the person that is receiving the threats, what they could be going through.. Tiktok could be an escape from someone’s home/work life.
