Thousands of demonstrators have marched through London in a day of protests.
Anti-lockdown and climate change demonstrations took place across Westminster, Lambeth and Southwark alongside some smaller protests.
The Metropolitan Police arrested 12 people in raids in three areas of the capital on Friday and confiscated items linked to the protests.
The arrests were “proactive action” to reduce the likelihood of criminal activity, the force added.
Officers seized bamboo structures, lock-on equipment and other items.
Those arrested have been taken into police custody as inquiries continue.
Thousands of protesters were seen marching through the streets of central London on Saturday.
Demonstrators packed the streets outside Downing Street.
Flares were set off while crowds shouted “shame on you” followed by prolonged booing.
Some protesters were seen throwing tennis balls at the Houses of Parliament.
One protester, who did not wish to be named, said: “They have little messages on them. Most of them are not very nice.”
