A senior manager of bikie-linked security company MA Services Group has been charged with threatening the safety of investigative journalist Nick McKenzie following a call allegedly made to his home on Christmas Eve.

Victoria Police said a 31-year-old man from Melbourne’s north-west was charged with two counts of using a carriage service to menace/cause offence by detectives from Taskforce Hawk, the special unit set up to investigate crime and corruption linked to the construction industry.

The Age and The Sydney Morning Herald have published a series of stories detailing the alleged links of MA Services Group to a bikie club, its subcontractors being accused of tax evasion and worker exploitation, and a sexual harassment scandal involving its founder, Micky Ahuja.

McKenzie is a multi-award winning journalist who works for The Age, The Sydney Morning Herald and 60 Minutes.
