Officer Carlos Manfredi says several people were detained for questioning after the shooting Saturday evening.

The shooting triggered a chaotic scene as dozens of people ran screaming as officers carrying handguns rushed to the scene.

Manfredi says a 64-year-old man who was caught in the crossfire got shot in the arm. He's hospitalised in stable condition.

Four shots were heard in a witness video posted online.

Manfredi says the argument had nothing to do with the gay pride event.

A concert that was part of the weekend-long gay pride celebration across the city was ending around the time of the shooting.
