A frightening scene emerged Friday at the legendary Art Basel Miami Beach as a woman was stabbed, causing some patrons to think they were watching performance art.

Miami Beach police spokesman Ernesto Rodriguez said the horrific incident occurred around 5pm at the Miami Beach Convention Center in a corridor near an art installation entitled 'The Swamp of Sagittarius,' created by Miami artist Naomi Fisher and partner Agatha Wara.

Police said the victim confronted the suspect, Siyuan Zhao, about purposely following her around the art show and bumping into her several times.

Zhao then pulled out an X-Acto knife and stabbed the victim in the right side of the neck and left shoulder without warning or provocation, authorities said.

The victim suffered several cuts, and a photo taken of her shows blood all over a white jacket that she was wearing as she sat on the ground covering her face while someone applied pressure to her neck wound with what appeared to be a white cloth.

She was taken to Jackson Memorial Hospital and is expected to survive.

Zhao was arrested immediately by a Miami police officer whom she made a shocking confession to.

While she was being patted down by the officer, she said, 'I had to kill her and two more. I had to watch her bleed,' according to Local 10 News.

Zhao admitted to stabbing the victim in the neck and she has been charged with felony attempted murder.

At the time of the stabbing, Fisher said she heard a scuffle at her exhibit and later saw the victim being wheeled away by paramedics.

'A guy walked up to me and said, 'I thought I saw a performance, and I thought it was fake blood, but it was real blood,' Fisher told the Miami Herald.

She explained that the stabbing happened in front of booth N29, where Freedman Fitzpatrick Gallery from Los Angeles was exhibiting.

'It's horrible ... I'm so freaked out,' Fisher told the Herald. 'I feel nauseous.'

Art Basel Miami Beach spokeswoman Sara Fitzmaurice said in a statement: 'The attack was an isolated incident that was immediately secured.

'The suspect was apprehended by police who were at the scene within seconds of the incident. ... Our thoughts are with the victim.”

Both the victim and Zhao were patrons of the art show and not exhibitors. The name of the victim has not been released.

Miami Beach police Det. Kathleen Prieto said that at least one witness thought it was a performance with fake blood until he realized that the blood was real and a woman had been stabbed

Another person thought the police tape around the scene of the incident was actually an art installation.

Earlier this week police and Art Basel officials announced that they had increased security in and around the convention center after the terrorist attacks in Paris.

Security guards and event organizers worked quickly to clean up the blood drops left at the scene of the stabbing, and to keep the public's attention focused on the art, the Herald reported.

Art Basel Miami Beach is attended by thousands of people from all over the world. The four-day fair closes on Sunday.

It is the extension of the annual contemporary art fair in Basel, Switzerland.
