jdm is quite correct, I too have never heard of any scams as far as ICICI is concerned, most other brokers have been involved in some sort of irregular practice at one time or the other even HDFC sec was caught up in the Gujarat IPO scam & were dirrected by SEBI to temporarily suspend the opening of new DEMAT a/c's but ICICI's reputation is untarnished, as far as I know.
