BREAKING 12.20pm: POLICE have arrested a 47-year-old man over the murder of Melbourne woman Sarah Cafferkey.
A Special Operations Group arrested the man about 12.30pm in the Melbourne suburb of Hawthorn about 12.30pm on Tuesday.
In a statement homicide detectives said the Bacchus Marsh man was "assisting police with their enquiries".
Ms Cafferkey, 22, went missing on November 9, with her car found six days later in the Melbourne suburb of Maribyrnong.
Her body was found in a Point Cook house on Saturday night after police executed a search warrant.
Police also reminded the community to refrain from posting comments on social media sites that could jeopardise any court matters arising from the investigation.
The investigation into Ms Cafferkey's murder continues.
8am: A man police are searching for in relation to the killing of Bacchus Marsh woman Sarah Cafferkey was jailed for stabbing a schoolgirl to death in 1986, and later tried to escape from Pentridge Prison.
Police have described Steven James Hunter, 46, as a ''person of interest'' in the investigation into the death of 22-year-old Ms Cafferkey, whose body was found at a Point Cook home on Saturday night, eight days after she went missing from Bacchus Marsh.
They have urged Hunter to come forward and speak to them.
It is understood that the house on Fongeo Drive is owned or rented by a friend of Hunter's - who Fairfax has decided not to name - and that Hunter knew Ms Cafferkey and exchanged Facebook messages with her in the weeks leading up to her death.
Reports at the time said the body was found slumped in the back seat of the car, with a petrol container nearby.
