Four people were arrested and two received fixed penalty notices amid further protests over the policing of the Sarah Everard vigil in central London.
Demonstrators again took to the streets of the capital on Monday afternoon and evening to continue to protest, blocking "a number of roads" and causing traffic disruption.
The Metropolitan Police said it had "maintained an appropriate policing plan" during the protest action around Parliament Square, Trafalgar Square and parts of the West End.

The Met Police have come under heavily criticism for violent scenes in Clapham Common over the weekend at a planned vigil for Sarah Everard, who disappeared on the streets of south London at the start of the month.
The demonstrators are protesting the police's handling over of the vigil, as well as the Government's Police, Crime, Sentencing and Courts Bill.

Many protesters chose to leave the area when encouraged to do so by officers on Monday afternoon, but others remained in the Westminster area, the Met added.
Temporary Deputy Assistant Commissioner Jane Connors said: "Whilst I understand why people feel the need to express their views at this time, we must remember that we are still in the middle of a pandemic, and that there is the constant risk of transmitting the coronavirus.

"Our officers were once again out on the streets, with the primary role of trying to ensure people's safety during this health crisis.
"Despite many people adhering to officers' instructions to leave the area and go home, we had to take some enforcement action as the evening progressed.
"Three people were arrested on suspicion of breaching the Health Protection Regulations.
"Two remain in custody and the third was released after being issued with a fixed penalty notice.
