HONG KONG (AP) — Hundreds of Hong Kong protesters have held a sit-in at a suburban train station to mark a month since a violent attack there by masked assailants on supporters of the antigovernment movement.

The protesters, many wearing black, flooded into Yuen Long station on Wednesday evening to commemorate the July 21 rampage by a group of men suspected of organized crime links.

They also wanted to draw attention to what they say is the lack of progress by police in investigating the attack, which left both protesters and passers-by injured.

The protesters observed a moment of silence, then covered their right eyes, a reference to a woman who reportedly suffered a severe eye injury from a police projectile.
