In what could be interpreted as the first strike on Prime Minister Najib Abdul Razak from within Umno, a police report has been lodged against his debt-ridden brainchild 1Malaysia Development Bhd (1MDB) and its directors.

The report filed by a Penang Umno division leader comes on the heels of former prime minister Dr Mahathir Mohamad's disappointment that the 1MDB issue was not raised during last month's Umno general assembly.
