KUALA LUMPUR: Fugitive financier Low Taek Jho often used random email addresses to send out his emails but there was one constant email among these and it was dealrainman1@gmail.com.

The High Court heard that Low, or better known as Jho Low, used the email to set his appointments with Datuk Seri Najib Razak's former special officer Datuk Amhari Efendi Nazaruddin and principal private secretary, the late Datuk Seri Azlin Alias.

Amhari, who was testifying on the third day of the 1Malaysia Development Bhd (1MDB) trial, said the same email was also used to send documents to himself and Azlin.

"The emails sent to me and Azlin by Jho Low were private and often sent through random email addresses.

"I confirm that the one email address he often used to fix our appointments and to send documents was dealrainman1@gmail.com," he said.

The witness said it was also common for Azlin to refer to Jho Low's emails by saying "dealrainman".

He said the emails from Jho Low would be sent to him (Amhari) at amharifnd@yahoo.co.uk and to Azlin at azlinalias@gmail.com.

"Usually, Jho Low would send the emails addressed to Azlin, and CC these to me.

"After the 1MDB issue blew up in public, Jho Low often locked the documents he sent to us," he said.

Amhari added that Jho Low would send the passwords for the documents to him and Azlin through BlackBerry Messenger.

The hearing before Justice Collin Lawrence Sequerah continues tomorrow (Sept 4).

Najib, 66, faces 25 charges – four for abuse of power that allegedly brought him financial benefit to the tune of RM2.3bil; and 21 for money laundering involving the same amount of money.

He was charged with four counts of abuse of power under Section 23(1) of the Malaysian Anti-Corruption Commission (MACC) Act, punishable under Section 24(1) of the same law.

He faces imprisonment of up to 20 years and a fine of up to five times the sum or value of the gratification or RM10,000, whichever is higher, if found guilty.
