The mother of the 'St Kilda teenager' says her family has received death threats.

She said some of the threats had been aimed at her 10-year-old daughter, saying they would cut her throat.

She was deeply distressed that people were targeting her innocent child and at claims she was a bad parent.

The 17-year-old girl who posted nude pics of two St Kilda players online and claimed she had a sexual relationship with Ricky Nixon undertook a lie detector test on Seven's Sunday Night program and the results were in agreement with her claims about her having had sex with the disgraced player manager.

The girl's father said he rued the day she had met the footballers at her school.

It has since transpired that the teenager has been 'stalking' Nixon at his holiday home over the weekend and by text. 

Police are now involved in the matter.
