Australian top-order batsman Usman Khawaja's brother, Arsalan Khawaja, was arrested by the counter-terrorism authorities over an alleged faked terrorism plot to kill senior national politicians including Prime Minister Malcolm Turnbull and his former deputy Julie Bishop.

Arsalan, who is charged with forgery and attempting to pervert justice, was arrested after a notebook which was found at the University of New South Wales (NSW) allegedly containing fabricated plans to carry out terror attacks in Australia.
