NEW YORK -- Police say six people wounded in a shooting outside the Empire State Building have been treated at a hospital and released.

The New York Police Department says three other victims are being treated for non-life-threatening injuries. One of them is being treated for elevated blood pressure.

A laid-off clothing designer fatally shot a former colleague near the skyscraper Friday morning. He then was shot dead by police officers during a confrontation that wounded the nine bystanders, who suffered graze wounds or other minor injuries.

Dramatic surveillance video shows the confrontation lasted only a few seconds.

Police say the officers responded appropriately when shooter Jeffrey Johnson pointed his gun at them.

WARNING: Video is extremely graphic.
