A well-known Hong Kong protester who disappeared from the city last August has returned to the city after being held in China, ex-lawmaker Eddie Chu has said.

Alexandra Wong, 64, was frequently spotted at anti-extradition bill protests last summer where she would wave a large Union Jack. She was last seen in Hong Kong on August 11 when she was surrounded by riot police outside Tai Koo MTR station. Wong was facing criminal proceedings over the border in Shenzhen, where she lives.

In a Facebook post on Saturday, Chu said that she is now undergoing a 14-day quarantine period after being held by Chinese authorities. He said that, until Tuesday, she was “awaiting trial on bail” for a year.
The former legislator added that Wong was in good spirits, though was treated at Tuen Mun Hospital on Friday after suffering an injury following a scuffle with mainland security officials.
Wong had previously told the media that she lived alone in the Chinese city and commuted across the border to join the pro-democracy demonstrations. According to a chronology she compiled, Wong said she was held at a detention centre in Futian on August 14 for “picking quarrels and provoking troubles.” The charge is often used against dissidents in the mainland.

Stand News reported that she was later transferred to Shenzhen No. 3 Detention Centre on August 30.
