Hong Kong ups crowd control measures after Seoul crush

STORY: Police also called on revellers to avoid gathering on steep slopes and steps in the city's nightlife hub, Lan Kwai Fong.

Costumed party-goers said they felt confident and safe going out to celebrate Halloween, thanks to the Hong Kong police's measures.

It comes after a deadly stampede in Seoul's popular Itaewon district on Saturday (October 29), when scores gathered for the first unmasked Halloween festivities in three years.

Chaos erupted when people poured into one particularly narrow and sloping alley, even after it was already packed, witnesses said.

Officials said 154 had been killed and 149 injured, with 33 people in serious condition.
