Video footage has emerged of pro-Palestine activists protesting against Hen Mazzig, a former Israeli Defence Force (IDF) lieutenant speaking at the University College of London.
The event which was organised by UCL Friends of Israel was relocated to another venue.
A spokesman for the Met Police confirmed they had been called to the Gower Street building at 7pm on Thursday 27 October.
He said: “Officers spoke to security at the university who were happy to let to demonstration go ahead on its grounds.
“They provided a policing presence during the demonstration. Police remained at the venue until the meeting ended safely.
“Following this, a woman made an allegation of common assault to officers and this is currently investigated by Camden police.”
A UCL spokesman said: “On 27 October, we did all we could to ensure that the UCLU Friends of Israel Society event could go ahead at UCL, working with our Security team and the Metropolitan police.

“It was widely advertised and open to the public, and as result a small but noisy group of protesters attended and occupied the rooms where the event was originally meant to take place.
“UCL Security found an alternative location and ensured the event went ahead safely. We regret protestors took measures to try to prevent the event from happening but stress that the protest was non-violent.
“We are aware that the Metropolitan police attended following accusations of assault and support them fully in their investigations.
“As this was a public event, it is unclear how many UCL students were present but we are instigating an enquiry and we will take appropriate disciplinary action where there is clear evidence that students may have breached our disciplinary regulations.”
Pro-Palestine human rights group Friends of Al Aqsa responded on their website by stating that the protests were entirely legal because it was peaceful.
