Demosisto says its chairman Ivan Lam was taken away by the authorities after flying into Hong Kong on Tuesday morning.



The pro-democracy figure had been charged in his absence last week for allegedly inciting others to join an illegal protest near police headquarters on June 21.



When the group's Joshua Wong and Agnes Chow appeared in Eastern Court on Friday to face similar charges, a prosecutor said Lam may not have been aware that he too had been charged.



Demosisto said Lam was stopped by officers at Chek Lap Kok at around 10am.



Meanwhile, the organiser of a July protest in Yuen Long, Michael Mo, was arrested at his home by police on Tuesday morning.



Mo was said to have been arrested on suspicion of helping to organise an unauthorised public gathering on July 27, when tens of thousands of people defied a police ban and marched through Yuen Long to protest against a gang attack on MTR passengers earlier in the week.
