Posting bank-related photos on Twitter

A friend of mine who works in a bank in Dubai, was sending me pictures of her work (taken from her computer monitor) to me which seemed to be confidential info of the bank. I sent an email to bank seeking advice who confirmed it is related to work and requested the pics to be deleted. She had cheated me some money and also sent a legal notice demanding more money. She also contacted my work place and tried to give me headaches saying I am a fraudster. I sent email to her bank informing the sme and they seemed to support her and ignoring my emails. I plan to post the pictures in Twitter and tag the banks support groups...and some of their customers and making everyone know that the bank lacks information security and their employees send banks info to outsiders. I wud like to know if this will bring me trouble....if the bank in Dubai can initiate any legal action from there.
