my little brother is being harassed and threatened by someone on xbox live

My younger brother is being harassed by someone on xbox live.

This person is making multiple accounts, being abusive and giving death threats .

We are reporting it via console but this is not stopping anything. This user needs banning , he is incessantly continuing .

What else do we need to do besides reporting and involving police.

In addition to what Smwutches stated you can also set your privacy settings to friends only so only people on his friends list can message him

Phone/chat support don't handle enforcement issues, so even if you contact them, they wouldn't be able to do anything. If you were to contact the police, they would need to contact Microsoft.

Reporting and blocking is all you can do through the console.

If someone harasses you or threatens you in the xbox live service just report that person and block him from further abuse. Remember in the future to not mention gtag of another gamer in the forums.

Only the Xbox Policy Enforcement Team can ban people from Xbox Live. If someone is threatening to ban or hack you, you should report this person immediately. Likewise if the person is spamming, harassing, or otherwise effecting your enjoyment of Xbox Live.
