Prize of 10 Million Dollars
E: scam through email

I would like to bring to your kind notice that i am an overseas student in australia. and i was tempted by a email that i have won a prize of 10 million dollers and i was asked to reveal my bank details as well as personal details . and in ignorance i gave my whole details to them .but due to the awareness of bank they could not withdraw money from my account but they have my passport details i want to know that what to do? and also want to inform the authorities about the deceivers who used the name of the bank i.e. hilton charted bank london

thanks
