Mr Farley later revealed himself to be the man at the centre of the incident, saying he was not a protester and was totally unaware the prime minister was visiting the city.
"I didn't see David Cameron. I didn't know it was David Cameron until they let me out of the police van an hour later," Mr Farley, who was eventually released without charge, said.

The 28-year old said he was on the way to his local gym for a session with his personal trainer when he crossed the road outside the council building.
"All I saw were a group of men in suits who came out of the Civic Hall."
He added: "It begs the question - how good is Cameron's security if I managed to run between it before they stopped me?"
Mr Farley, who was carrying a towel but no ID at the time, said it had been "harrowing" to find himself "harangued and manhandled" by police and not being told why he had been arrested.
"I'm quite shook up. I was almost in shock, like I'd been in an accident or something."
The media reaction to the incident had been "insane", he said, adding that many of his friends wanted to buy him a drink and he could see the "funny side".

"I kind of wish I had been protesting something or I had had something to say", he added.
'No threats'
Following the incident, Chief Inspector Derek Hughes of West Yorkshire Police said: ''Around midday, a 28-year-old local man was briefly arrested after he came close to the prime minister's group who had just left the Civic Hall in Leeds.
''No threats were made, and after the man's details were checked, he was de-arrested and allowed on his way.''
