Please help me, my brother gained 30k in a fraudulent transaction

So… my brother owns this beefy finance server and will spam post phishing links to try and lure people into giving their money away. Primarily crypto related. Some how, this sucker clicked one of the links and submitted a transaction connected to his ledger and my brother saw blood in the water. He saw the 30k, drained the wallet and dipped. He’s afraid that this guy could potentially tack him so he asked me to ask for help.

is there any way to hide this from the police? we live in canada and this is life changing money for us. it will finally allow us to move from the bridge we live under and give us access to hot food and water.
