I had 2.8 bit coins in my mtgox account and last night I received an email telling me that my account had a withdrawal. The email told me to email back if the transaction was unauthorized. I emailed them back right away confirming that the withdrawal was not authorized. They emailed me back the next morning saying it was too late to stop the transaction it had already been processed to an IP address in France. There is nothing we can do about it. Please report the incident to your local police. They handle these transactions and had allowed this to happen and took no responsibility at all.
