Nooryana Najwa, the daughter of Najib Abdul Razak, is claiming that banks are rejecting the family's bid to open a fresh account to receive public donations for her parents' hefty bail amounts over multiple money-laundering charges.

Taking to Instagram, Nooryana alleged that banks were not allowing the Najibs to open an account for fear of being seen to be helping the embattled former prime minister.

Her father has been hit by a total of 32 charges for alleged offences related to 1MDB and its former subsidiary SRC International, while her mother Rosmah Mansor was on Thursday charged with 17 counts of money laundering.

"The past month has indeed been challenging for my parents. Lawyers' fees aside, the bail posted for my parents has now reached RM6.5 million.

"We have been drawing on the kind help of relatives, the tabung (fund) which was collected earlier for my dad, and my parents' savings.

"My dad has even been forced to dip into his savings account," she said in her post. 

Nooryana claimed that her brother Ashman's attempts to open up a bank account has met with resistance.

"Since my father was charged for the third time two weeks ago, my brother Ashman has been trying to open up a bank account to start another tabung to collect donations from the public.

"However, he has met with little success, as the bank officers have privately told him that their senior management is fearful of being seen to be helping my dad, and his many requests to open up a bank account have been rejected," she posted.

Nooryana then called on banking institutions to forsake any fear of "government pressure or reprisal" and come to the family's aid, "in the interest of fairness."
