Hong Kong 'acid attack' hurts 30

Version 0 of 1.

Thirty people were treated for injuries in Hong Kong after they were splashed by a corrosive liquid.

Two bottles of what is thought to be acid were either thrown or fell from a building into crowds of shoppers in the Mong Kok district.

Those who received medical help - 14 women and 16 men - suffered burns to the legs, arms and faces.

Police are linking it to an incident in December when 46 people were hit by acid on the same street.

No-one has been arrested in connection with either incident.

Reward offered

Police say whoever is responsible faces a possible charge of intent to cause grievous bodily harm, which can lead to life in prison.

After the December incident, police offered a reward of $12,900 (£8,000) for information leading to an arrest.

"We will find out whether the two cases were done by the same person as soon as possible," said Superintendant Leung Ka-ming.

Firefighters helped those affected clean the liquid from their arms and legs before sending them to hospital.

Samples of the fluid are being tested in a laboratory to determine exactly what it is.
