KUALA LUMPUR (Bernama): The validity of signatures on key bank documents for millions of ringgit of transfers was raised by Datuk Seri Najib Tun Razak's defence team during the trial of his 1Malaysia Development Berhad (1MDB) case at the High Court here on Wednesday (May 19). The issue, however, was objected to by the prosecution. Najib's counsel Wan Aizuddin Wan Mohammad brought up the issue when cross-examined the former chief executive of 1MDB Mohd Hazem Abd Rahman. Wan Aizuddin: Look at the signatures on the transfer instructions involving millions of ringgit from 1MDB Global Investments Limited (1MDB-GIL) to several other entities. Do you know whose signatures were there?
