Former TV host Andrew O'Keefe has been charged after allegedly threatening a man at a home in an exclusive Sydney harbourside suburb.

Police stopped the 52-year-old in a Mercedes sedan about 11.45am on Sunday in Bellevue Hill.

He had allegedly threatened another man just down the road at a home on Longworth Avenue, Point Piper, shortly before his arrest.

A roadside drug test and a second oral fluid test at Waverley police station allegedly both came back positive and the sample was sent for analysis.

O'Keefe was charged with contravene prohibition/restriction in AVO and stalk/intimidate intend fear physical harm and refused bail, to front Waverley Local Court today.

He escaped jail earlier this year after being found guilty of multiple domestic violence and drug offences including assault causing actual bodily harm, breaching a domestic violence order and possession of the synthetic stimulant drug mephedrone.
