The man who threw a milkshake at Nigel Farage said his protest wasn't planned.
Paul Crowther, 32, threw the drink at the leader of The Brexit Party on Blackett Street on Monday afternoon.
Mr Farage was visiting the city ahead of the European Parliament elections on Monday but his campaigning was cut short by the incident.
Mr Crowther, from Throckley, was arrested on suspicion of common assault and led away in handcuffs.
Speaking to the Press Association immediately after Mr Farage was drenched in milkshake, he said: "I didn't know he was in town, I thought this is my only chance."
Mr Crowther said he saw there was a Brexit Party event in the city centre, thought it was an MEP and then saw Mr Farage.
He explained: "It's a right of protest against people like him.

"The bile and the racism he spouts out in this country is far more damaging than a bit of milkshake to his front."
Despite being arrested, he said he did not regret his actions and denied an allegation someone was cut, saying he only threw sticky liquid on the politician.
Of his milkshake, he ruefully said: "I was quite looking forward to it but I think it went on a better purpose."
Mr Farage was left covered in the drink - a £5.25 banana and salted caramel milkshake - and was bundled away by his security staff.
He was visibly shaken and could he heard telling his security staff "this is a failure" and "how did that happen?"
Afterwards, Mr Farage tweeted: "Sadly some remainers have become radicalised, to the extent that normal campaigning is becoming impossible.
"For a civilised democracy to work you need the losers' consent, politicians not accepting the referendum result have led us to this."
Last week, police apparently ordered a McDonald's outlet near a Brexit Party campaign rally to stop selling milkshakes and ice cream, according to the restaurant's staff.
Earlier, Northumbria Police said it had not asked local fast food outlets to stop serving milkshakes to deter similar protests.
There were no pre-planned protest there to greet Mr Farage when he arrived as his visit was not pre-announced.
