Compromised Seed Phrase - Stolen all my bitcoin

Hi,

Really hoping someone can help me. I have just opened my Ledger Wallet to find £0 showing. And it looks like there has been a 'Sent' operation on 12th August 2025 for all my btc.

Are there steps I can perform to help understand what happened and where my btc is?

If someone could help i'd really appreciate it.

Thanks in advance.
