A Twitter user known as Cidz Carnage or @carnageofficial, thought to be the youth involved, tweeted on Tuesday:
'Oi some racist women was giving it to me today, then she hit me with a bottle then i f***ed her over dumb b****.'
He later added: 'Calling me a smelly african... Then having the audacity to hit me with a bottle.' And yesterday he posted: 'Remember Racism is Disgusting and Totally Unacceptable'.
He later deleted the tweets.
