An Australian activist has been arrested and detained in London just 20 minutes into a protest outside the Chinese embassy after authorities alleged he had emailed a bomb threat.

Drew Pavlou, a 23-year-old Australian activist who has been critical of China's human rights record, held a small protest outside the embassy, displaying a number of flags.
