“I must have counted at least five officers situated there.
“When I saw the police response I thought there must have been a full scale riot going on nearby.”
He added: “It is maybe more common to see this type of emergency response on a weekend.
“Police appeared to be questioning one male and a nearby doorman outside the Pure Gym in connection with what had happened.
“I’m not sure if it had maybe been called in as something worse initially and that’s why so many had turned up.”
Another man added: “I’d driven past and saw the police parked on West Marketgait on the central reserve.
“I know it isn’t a surprise to see police in the city centre but I was still quite shocked when I saw all the vehicles there.”
He added: “You think the worst when you see this type of thing going on.”
A spokeswoman for the force added: “A man was arrested and another given a warning after a disturbance in West Marketgait, at 1am..”
