It marked the third night of chaos which has spread to some of the country’s biggest cities, including Wuhan, the first epicentre of the coronavirus almost three years ago.
On Sunday night, the BBC said one of its journalists, Ed Lawrence, was working as an “accredited journalist” when he was “beaten and kicked by police” while covering the protests.
Footage on social media showed him being dragged to the ground in cuffs, while in another video, he was seen saying: “Call the consulate now.”
According to officials, Mr Lawrence was arrested “for his own good” in case he caught coronavirus from the crowd, but the BBC said it was “extremely concerned” about his treatment and added: “We do not consider this a credible explanation.”
They also saw several people on the streets of Shanghai being arrested by police on Monday morning.

Sky News witnesses Shanghai protest
Meanwhile, protest against President Xi Jinping‘s zero-COVID lockdown policy has spread outside the Far East, with between 100 and 300 people gathering outside the Chinese Embassy in London.
A woman from a group called China Deviants told Sky News they had decided to voice their anger against President Xi’s regime because “people in China are being oppressed”.
She added: “We have been oppressed for years, for decades, and we want to change that. We need to stand up against this authoritarian regime.”
She said, like many of her fellow countrymen and women in China, their anger had boiled over after a fire in the city of Urumqi on Thursday which killed at least 10 people.
The city has been under harsh lockdowns for more than three months to combat the spread of the coronavirus under China’s “zero-COVID” policy.
Videos on social media had showed an arc of water from a distant fire truck falling short of the fire, sparking waves of angry comments online. Some said fire engines had been blocked by pandemic control barriers or by cars stranded after their owners were put in quarantine, but this has not been verified.
The woman, who covered her face for fear of punishment, said: “It sparked rage. We stand up to raise voices for those people. We stand for justice.
“We want to speak, and we want people to hear it.”
China Deviants is a non-profit group and is calling for others to join them to “reject dictatorship”.

A statement from the group said: “We are committed to awakening the Chinese people against the dictator, letting the Chinese people and the international community realise that: a non-elected government cannot represent the voice of the Chinese people.
“We need democracy and freedom, and we reject dictatorship.”
As protesters returned to Shanghai, Amnesty International described their move as one of “remarkable bravery”.
