Man found with ingredients for smoke bomb at Legco copyright rally: Lighters, masks, gloves also found
Police stop man heading to anti-copyright rally with 1kg of potassium chlorate

Police have found an explosive ingredient on a 20-year old student they said was heading towards the heavily secured rally at the Legislative Council on Wednesday.
The man was detained after police found on him a kilogram of potassium chlorate, locally dubbed “smoke cake”, in eight separate pieces, Senior inspector Clement Li Ka-ming of Hong Kong Island Regional Crime Unit said.
“Burning just two grams of the chemical will make a large amount of white smoke. So you can imagine how it could stir up panic in a crowd if 1 kg of it was burned,” Li said.
It is also an ingredient in gunpowder and fireworks and creates intense flame. Instructions to make and use the chemical can be found on YouTube.
