Trying to remember Asian film title, hope you can help

Asian movie a line of security guards or police officers are lined up outside a building in a carpark,
A reporter is talking then 1 hooded man appears in car park, next minute an army of hooded men, they attack the police type guys, when the hooded men get shot they go down but get back up, they are running upstairs in a the building, again when they get shot or fall about 5 floors to the ground all twisted and broken they get back up,
There is a man in the building petrified because they are after him.
The police in the office with him try to get out of the building, i think, if one of the hooded men get to him they kill him by touch. hope someone can help.
