When the officers arrived, police said, Vassell took a two-handed shooting stance and pointed an object at them.
The video clip ends with Vassell brandishing the shower head like a pistol at something off screen - which authorities claimed were the responding officers, who then opened fire.
Protesters marched through Crown Heights in Brooklyn, New York, on Thursday, April 5, to remember Saheed Vassell, a local man shot dead by police the previous day.
A tense crowd gathered after the shooting, with some people shouting at officers and decrying the killing as another example of an unarmed black man dying at the hands of police officers who overreacted.
Mr Vassell's father, Eric, said his son had bipolar disorder, The New York Times reported.
Clarke on Thursday welcomed the announcement by New York State Attorney General Eric Schneiderman that he will conduct an investigation into the police shooting death of an emotionally disturbed Jamaican national Wednesday evening.

Rain eases to showers overnight and Friday looks mainly dry through the Capital Region - a welcome break between systems. There is going to be about a 30-degree temperature difference between Friday afternoon and Saturday morning.
Footage shows a man that police believe to be Saheed Vassell holding a gray object and pointing it at people. Although he admitted that pointing a pipe at people may have caused panic, Eric Vassell said the officers acted rashly.
"Better they should have some police who know people in the community", Willie said.
"As a society, we have to make the message "Black Lives Matter" clear on our streets, clear to all charged with law enforcement, and up and down our justice system", he said. "There's a guy walking around the street. He looks like he's insane, but he's pointing something at people that looks like a gun and he's like popping it as if...like if he's pulling the trigger". The younger Vassell's mental disability was allegedly well known by both his neighbors and local police, according to the Times report. They should not train them to kill. They always have a choice. "They should train them to protect life, to save life as much as possible".
Still, there are some tough questions surrounding this case, specifically about how neatly it fits into the narrative of other controversial fatal police shootings of black men and the role of community policing in incidents just like this one. Stephon Clark, an American black man who was shot dead last week after two law enforcement officers misunderstood him as an accused of breaking auto windows in California, was shot eight times in his back, according to an independent autopsy.
Saheed's mother, Lorna Vassell, said, at the vigil and protest, that her son came from a good family, adding that the police "have no right to shoot him down the way how they did it, because Saheed is no gunman". "It's very hard to come forward", Deputy Police Commissioner Susan Herman said.
