12名涉反修例案件的港青疑在潛逃往台灣時被中國海警截獲，被秘密關押接近兩個月，事件備受國際社會關注。負責協助12港人的鄒家成、朱凱迪、黃之鋒和岑敖暉10月20日起，通過區議員派發5萬張印有「#拯救12港青 #Save12HKYouths」的透明卡，上面印有12名被送中港人的姓名，呼籲市民將透明卡帶到各個地方並拍照上載到社交媒體，提醒市民關注12港人的情況。
黃之鋒發指今次運動參考中國維權人士、因煽動顛覆國家政權罪而被捕的聲援甄江華行動，當時也有人印製透明卡。
鄒家成說，12港人關注組本周日（25日）會舉行「國際連動、聲援12港人」的網上集會，將會有12港人家屬及講者發言，期望集結國際力量，促中共立即釋放12個被拘留香港人，超過30個城市也會在本月23至25日舉行集會遊行聲援。
12 Hong Kong youths suspected of being intercepted by Chinese Police while fleeing to Taiwan, are secretly detained for about 2 months and attracting international attention. A concern group led by Chow Ka-sing, Eddie Chu, Joshua Wong and Lester Shum plan to distribute 50,000 transparent cards printed with “#Save12HKYouths” through District Councillors. Citizens are encouraged to take pictures with it in various locations and post to social media to raise awareness.
Joshua Wong said this campaign mirrored the movement to save China’s rights activist Zhen Jiang-hua, who was arrested for inciting sedition.
Chow Ka-sing said that the Concern Group will hold an online rally “International Connection, Support 12 Hong Kong Youths” this Sunday (Oct 25), which will include family members of the 12 youths and other speakers, to garner international support to prompt their release. Over 30 cities worldwide will hold rallies and marches on October 23-25 in support.
