A man has been charged with stalking media personality Jackie O Henderson after being arrested in Sydney’s eastern suburbs.

Officers arrested 38-year-old David Gourlay in Clovelly shortly before 10.30am last Thursday, a day after reports emerged that Ms Henderson, 50, was being followed and harassed.

Police say they began investigating on July 3 after receiving complaints that the radio host was being stalked by an unknown man in the area, reported The Daily Telegraph.

During a search of Mr Gourlay, officers allegedly found an improvised weapon in his possession. He was taken to the hospital for a mental health assessment and discharged the following afternoon, shortly before 4.40pm.

He was then taken into police custody and later charged at Waverley Police Station with multiple offences.

This included four counts of stalking or intimidating with intent to cause fear or harm, using a carriage service to menace or harass, being armed with intent to commit an indictable offence, and possessing an offensive weapon with intent to commit an indictable offence.

Mr Gourlay was refused bail and is expected to appear in court today.

An interim apprehended violence order (AVO) has also been issued to protect Henderson.

The radio host is currently on a winter break from her top-rating Kiis FM breakfast show and is holidaying in Fiji with her daughter.

More to come.
