The Bonneville pub on Lower Clapton Road - which describes itself on twitter as 'Hackney's latest and greatest bar and restaurant' - angered residents after a series of tweets at the weekend.
It tweeted: 'CSIClapton due to events on Lower Clapton Road this evening, we will unfortunately have to close #WelcomeToHackney'.
In response to a tweet from @dreyfuscafe...
The Bonneville replied 'some kid got stabbed over the road and decided to run into ours. Great look for our first week.'
A wrecked blue car thought to be an Audi lay across a central reservation next to traffic lights close to the Lee Valley Ice Centre.
The N38, with destination of Walthamstow Central on the front, stood nearby, its right front corner crumpled and its right side angled into a grassy verge.
