A university has said it will "not tolerate" any form of discrimination after what it described as antisemitic graffiti was found painted on a campus building.
Two messages were daubed onto the Lasdun Wall walkway at the University of East Anglia (UEA) in Norwich.
A spokesperson said the graffiti would be removed and said it was working with the police to identify those responsible.
In a letter addressed to students and staff, UEA vice-chancellor and president David Maguire said there had been a "rise in instances of antisemitism" at the university.
"We will not tolerate antisemitism, Islamophobia, or any form of racism, hate crime, harassment, or discrimination here," said Mr Maguire.
"In recent days, we have sadly witnessed a rise in instances of antisemitism across our community, including graffiti on our campus walls, comments made during a university event, and inappropriate comments on social media.
"This is unacceptable and we are taking action to ensure that perpetrators are dealt with swiftly.
"For the most serious offences this could include disciplinary action and a police investigation."
