Umno's cyber warfare chief Ahmad Maslan says there is no need to go into details over claims that Prime Minister Najib Abdul Razak received Bank Negara's clearance to transfer RM2.6 billion into his personal bank accounts.

Umno supreme council member Puad Zarkashi revealed this in a speech in Australia last week, but Ahmad said this was an "old story".

"This was a long time ago. Why do we want to revive old stories?" Ahmad asked when questioned on this at the Parliament lobby today.
