Two men fighting in the middle of Sheffield city centre has sparked a big police response.
Officers were called to York Street at the junction of Fargate at around 2.40pm today as a fight spilled from outside Santander Bank to the Sainsbury's Local loading bay around the corner.
One eyewitness said a third man 'held a knife' to one of the assailant's throats before police arrived onto the scene.
Shoppers and workers looked on in amazement as the two men traded blows. A riot van and four police cars arrived minutes after the fight broke out.
The eyewitness said: "One of of the men was on top of the other hitting him and another man out of nowhere told him to get off him before putting a knife to his throat.
"It was crazy, complete madness."
Officers detained one man involved in the fight - it is not clear at this stage if any other arrests were made.
