Mr Pavlou said he was detained for 23 hours before being released at 3pm the next day.
“Officials from Australia’s High Commission in London will raise Mr Pavlou’s claim that he was denied consular access before being released with UK authorities,” the DFAT spokesperson
Mr Pavlou said that while his passport was returned, he was strongly recommended to remain in the UK until 14 August when he is required to attend the police station.
Chief executive and co-founder of prominent group Hong Kong Watch Benedict Rogers has thrown support behind Mr Pavlou, describing Mr Pavlou’s experience as a “totally absurd and outrageous injustice”.
SBS News has requested comment from London’s Metropolitan Police and the Chinese embassy in the UK.
