“I have no doubt there will be more to come”

Deputy Assistant Commissioner Laurence Taylor, who led Saturday’s police operation, said: “Public order policing does not end when protesters return home.

“We have teams of officers who continue to build cases against detainees and initiate investigations into those who come to our attention when images and videos are shared on social media.

“Since the end of yesterday’s demonstration we have issued appeals in relation to six incidents and I have no doubt there will be more.

“Our colleagues at British Transport Police have issued two further appeals. “We urge anyone with information regarding the identity of the suspects, or who has images or photographs of other possible crimes, to get in touch so we can take appropriate action.”
