Their attacker had locked himself in his Tsing Yi flat over a minor traffic offence
Four policemen suffered severe chop wounds after being attacked by a man who had barricaded himself into his Tsing Yi flat after another officer tried to serve a summons for a minor bicycle offence.
The emergency unit officers, armed with batons and riot shields, were injured after they smashed their way into the flat to confront the man, who was wielding two 30cm knives.
Three of the officers were in serious condition at Yan Chai Hospital, while the fourth was in stable condition last night.
All of the officers, aged between 30 and 35, suffered severe slash wounds.
Their unit had been called to the ninth floor of Yee Yat House in Tsing Yi Estate at about 4.40pm after a traffic officer tried to serve the summons on the 45-year-old man, surnamed Lee. Police said the officer was punched and threatened with a folded chair.
