The demonstrator carrying the swastika sign was one of two people arrested under section 5 of the Public Order Act 1986 for causing harassment, alarm and distress at a rally in central London.
In recent days, law enforcement in Ohio and California have announced the arrest of alleged perpetrators of a high volume of swatting activity and false bomb threats.
One protester carried a sign that compared Jews to Nazis via a blood-spattered swastika intertwined with a Star of David and the words, “The irony of becoming what you once hated.”
The door of the synagogue was defaced with swastikas and symbols representing the KKK movement.
Around 20 people carried Nazi flags and walked up to the Wisconsin State Capitol in Madison before heading to James Madison Park for a neo-Nazi rally.
The discovery comes amid a global spike of online antisemitism after the October 7 terror attacks by Hamas in Israel.
The Cleveland Jewish Federation called the vandalism "absolutely sickening."
The vandalization came shortly after social media accounts for the 2nd Avenue Deli posted pro-Israel content.
The judge presiding over the case ruled that the principal failed “to take appropriate and reasonable steps to discourage and modify the antisemitic student bullying and harassment behavior.”
