Police in Australia have arrested a teenager accused of making death threats against Israeli President Herzog.
The 19-year-old was charged with making the threats "toward a foreign head of state and internationally protected person".
While police did not name Herzog, who is scheduled to arrive in the country for an official visit on Sunday, he was widely reported to be the target in Australian media.
The suspect was denied bail and will appear in a Sydney court on Thursday. If convicted, he faces a maximum sentence of 10 years behind bars.
During his trip, Herzog is scheduled to meet the families of those killed in the Bondi Beach massacre in December.
The Islamic State-linked terror attack saw 15 people killed when father and son terrorists Sajid and Naveed Akram opened fire on a Chabad Chanukah event.
Sajid was shot dead by police at the scene, while Naveed was badly wounded. He was released from hospital last month and transferred to the Goulburn high-security prison, where he awaits trial.
However, Herzog's visit has prompted a significant backlash from anti-Israel activists, who have launched a campaign to have it cancelled.
Protests are planned in several major cities, while, in light of the "significant animosity" against the president, police in New South Wales (the state in which the Bondi attack took place) announced an extension of the stringent restrictions on unapproved protests put in place following the shooting.
New South Wales premier Chris Minns announced in December that his government would “move to restrict the authorisation of public assemblies in designated areas following a terrorist incident, to protect the community, prevent intimidation and allow police to focus on keeping people safe”.
Under the new measures, when a terrorist incident is declared, the state’s police commissioner can identify “specific areas where public assemblies are restricted for a limited period”.
"That might be any part of the state or all over the state. No public assemblies in a designated area will be able to be authorised, including by a court,” the announcement added.
Each declaration requires the agreement of the state’s policing minister and can last for up to three months.
Police have also been empowered to “move people on” if they cause “harassment or intimidation” or obstruct the road.
Australia's deputy prime minister, Richard Marles, told ABC Herzog's visit would be treated just like that of any foreign leader and that "he will be a welcome and honoured guest".
