Swiss AG says "serious suspicion" of Swiss banks being involved in alleged 1MDB graft

SINGAPORE (Reuters) - There was serious suspicion of Swiss banks being involved in alleged criminal activities linked to Malaysian state fund 1Malaysia Development Berhad (1MDB), Swiss Attorney General Michael Lauber said on Wednesday.

"The analysis of all the financial documents brought up serious suspicion of the possible implication of Swiss banks in these alleged criminal activities and of an abuse of our financial place to deceive legitimate Malaysian sovereign funds," Lauber said at an event in Singapore.

Lauber did not name the banks, but Swiss authorities have only formally launched a criminal probe against Swiss private bank BSI.

Malaysia's 1MDB, once a pet project of Prime Minister Najib Razak who chaired its advisory board, is the subject of money-laundering investigations in at least six countries, including Switzerland, Singapore and the United States.

Najib has denied any wrongdoing and said Malaysia will cooperate with the international investigations.
