Stolen funds have been tracked to an Electrum wallet, can anyone advise as to ANY possible options to return those funds, and or seize the wallet.
The funds are never "in a wallet". The funds are, to say it simple, always on the blockchain. The wallet software only helps handling those funds if one has - in a way or another - the private key stored in the wallet.
This being said, a non-custodial wallet like Electrum works in a way that the owner has the private keys, as opposed to custodial wallets where the custodian is the actual owner (according to the network) and one only has an account there from where he is usually allowed to withdraw. In this case the authorities can get in touch with the custodian. Now, since Electrum is non-custodial, you simply don't know who has the private key. Even more, that somebody can use Electrum today and recover his wallet in Sparrow, Blue Wallet or even Bitcoin Core tomorrow if he wants to do that.
So the Electrum "part" doesn't help you that much (if it's actually correct). It just helps you know it was a non-custodial wallet. But you cannot seize anything, it's just a free software with its source code free to download. It's just a tool.
If you want to get to the point of seizing anything, you have to keep an eye on those funds and see if they touch a KYC exchange. Then you can have a case and then the authorities should contact the exchange ASAP.
