A teenage former terror suspect who had charges against him dropped for lack of evidence has been hit with a highly restrictive control order that restricts him to worshipping in one mosque only, and wearing an electronic monitoring bracelet.

Harun Causevic, 18, was one of three young men initially charged with being a part of an alleged Anzac Day terror plot at Melbourne's Shrine of Remembrance. The charges were dropped last month after the Commonwealth Director of Public Prosecutions deemed there was not enough evidence.

But last week, the Australian Federal Police applied successfully before a federal magistrate to impose severe restrictions on the young man, using substantially the same facts as were presented in the original case.

The restrictions comprehensively control Mr Causevic's movements, both in the real world and online.
