Traffic was backed up while two men exchanged punches in a suspected road rage incident in Cambridge today.
Police arrested a 35-year-old man in connection with the incident on Victoria St, near the Duke St roundabout, which occurred about midday.
He was been let off with a "pre-charge warning" and will not be appearing in court.
Matt Cummings, who works at the nearby Deli on the Corner, said a car was cut off by another vehicle as they emerged onto Victoria St from the roundabout.
The drivers of both vehicles tooted their horns, before both cars pulled over near the pedestrian crossing on Victoria St, in front of dozens of people having breakfast at adjacent cafes.
