Since the attack, a number of people have been charged by police after allegedly offensive messages were posted on social media websites.
These include a 22-year-old man from Lincoln, a 28-year-old man from London, a 23-year-old woman from Southsea, and a 19-year-old man from Woking.
Three men - two from Gateshead and one from Stockton - have been arrested by Northumbria Police on suspicion of posting racist tweets.

Having seen some very offensive posts (to my mind) about Drummer Rigby's murder including one FB group saying that "
Lee Rigby was a rapist and deserved to die", no one has been arrested over these posts yet.
