Woolwich stabbing

Quite worryingly I can't seem to find much news coverage on this but Woolwich station was closed following a stabbing on Wednesday night. There also appears to have been two retaliation acid throwing attacks which resulted in both Lewisham hospital and Woolwich hospital being closed whilst the fire brigades tested the chemicals (assume to make sure they weren't Chemical Ali style).
All of this took place on a train around 8pm, hardly late and I should imagine still full of commuters. Yet there is a short piece on this on one online site and nothing at all on the news or in any other press.
I asked a taxi driver what it was all about and apart from a racist rant he was very vague about the whole thing as if he had been told not to talk about it. Very odd indeed.
I have no idea why local hospitals being closed and yet another gang stabbing isn't local news but the last two days have seen the trains and stations manned with police which is a good thing although rather a case of after the horse has bolted...I guess it is incase there is any more retaliation. Be interested to hear if anyone else has heard about this.
