Leading Hong Kong democracy activist Joshua Wong was arrested on Friday, his party said, a day ahead of a planned rally in the city that has been banned by police. His arrest came just hours after the reported detention at Hong Kong's airport of a vocal independence campaigner, and as Beijing continues to pile pressure on the anti-establishment movement in the city.

"Our secretary-general @joshuawongcf was just arrested this morning at roughly 7:30," Demosisto tweeted. "He was forcefully pushed into a private minivan on the street in broad daylight. Our lawyers following the case now."
