Not an ordinary Wednesday at TTG Towers.

Myself and colleagues were startled an hour ago as about eight police cars and vans sped along Blackfriars bridge – the wrong way – and stopped just outside our office.

Then they were off again. Several other colleagues in our building, on the south side of Blackfriars bridge, spotted the commotion and tweeted the news…

Sky News reported on the incident, which reportedly involved a police officer being shot my a man running around Waterloo’s The Cut area with a sub machine gun.

Once again – Twitter revealing its use as a news source. Follow the live feed here.
