Pro-Tibet protest on Tower Bridge

James Murray is being questioned by police

Four people have been arrested after a man scaled Tower Bridge in a protest about Tibet.

James Murray, who belongs to Students for a Free Tibet (SFT), climbed suspension cables reaching a height of 100ft above the River Thames.

He unfurled Tibetan national flags and a 37 sq ft banner declaring the message "Free Tibet", before coming down.

A police spokesman said four people have been held for public order offences.

A spokesman for SFT said a woman who was stopped from scaling Tower Bridge and two other "ground support" members, are being questioned by City of London Police.

The demonstration in London coincided with a protest in Beijing by campaigners from the same group.

Mr Murray, an Edinburgh University student, said: "The Chinese government is using the Beijing Olympics in an attempt to legitimise its brutal occupation of Tibet and cover up its human rights record.

"We are here in solidarity with Tibetans to support their cries for human rights and freedom.

"At this critical moment, we hope to shine the Olympic spotlight on China's occupation of Tibet."
