HONG KONG (AP) — Hong Kong's Apple Daily newspaper says the outspoken head of its publishing group, Jimmy Lai, has been held by police over his participation in a protest march in August that was part of the territory's months-long pro-democracy movement. 

The paper said Lai was picked up from his home by officers early Friday. It also said the vice chairman of the opposition Labor Party, Lee Cheuk-yan, and others were also detained at the same time in connection with the Aug. 31 march. 

Hundreds of thousands of people defied a ban by police on the activity that like similar actions ended in violent clashes between police and protesters.
