A MALE was left "spitting blood" after violence erupted in the city centre today.

It is believed three individuals were in an altercation with a 19-year-old male in the early afternoon.

Police were called to reports of an assault in the Bank Street area at around 12:18pm.

A witness, who called police, described how the fight broke out on the stairs heading up towards the exchange, near Bradford Crown Court.

She said the whole group seemed to be college-aged students, with three of them rounding on the one victim.

The injured male was "spitting up blood" after the attack, the witness said.

She added: "He told me they'd punched him in the privates.

"They ragged him about.

"There was a group walking up Drake Street, talking and shouting, and I didn't think anything of it.

"But then it kicked off.

"Luckily I was here, otherwise God knows what they would've done."

Police arrived after the attack and parked up on Drake Street.

The victim could be seen entering the vehicle to give a statement.

After, the injured male was taken to hospital to be assessed.
