Police are aware of a video circulating online which shows an officer using force after a man had tried to enter a restricted area in Whitehall SW1.
The actions of the officer will be looked at in the wider context of this incident.
The man had previously been asked to wait while the restricted area was opened up and he would be able to attend the Cenotaph.
The road was closed off as the Remembrance Sunday event this year was a closed ceremony due to Covid restrictions.
The area was later opened up to members of the public.
A man, aged 47, was arrested on suspicion of common assault on an emergency worker. He was taken into police custody and subsequently released under investigation.
Officers have been made aware of another video circulating online appearing to feature the same man claiming that he had deliberately provoked officers. This will form part of ongoing enquiries.
