Four men have been arrested following protests at Queen's University Belfast by anti-war protesters.
They were detained during a demonstration against former US Secretary of State Hillary Clinton, who is the university's chancellor.
She was attending the final day of the Global Innovation Summit, taking place on the campus, and footage showed pro-Palestinian protestors facing police officers at the gates of the campus.
The PSNI said four men had been arrested following public order offences.
They were arrested on suspicion of "numerous offences", a PSNI spokesperson said.
There were scuffles with other protesters as officers tried to leave the scene with those who had been detained.
In a statement, Queen's University said that while they respected the right to protest peacefully, it was "disappointed at the action of this small number of protesters and condemn their behaviour".
Earlier, Ms Clinton said that Belfast was "quickly reinventing itself" after the end of decades of conflict.
"You've heard so much over the course of the last few days about Belfast, (a) city that is quickly reinventing itself and one of the main reasons, I would argue, is because of the end of conflict, which I was very - like so many of us - gratified to see".
Ms Clinton said looking to the future was key for the city after the problems of the past.
"We had an extraordinary conference here a year-and-a-half ago to celebrate the Good Friday Agreement, the end of conflict, a moving away from the past to look towards the future, the very strong relationship that this university, in particular, but others have with the business community, forging public-private partnerships.
Ms Clinton, who became the first female chancellor of Queen's University in Belfast in 2021, said she could not express how pleased she was to be there, while a pro-Palestine demonstration was held outside to protest her visit.
The PSNI said officers would remain in south Belfast this evening and a full investigation would follow in due course.
