The four NYPD officers involved in the fatal shooting a disturbed Brooklyn man in April were identified on Friday, sources said.

Officers Leon Dingham, Anthony Bottiglieri, and Bekim Molic, from the 71st Precinct, and Omar Rafiq, from the department’s Strategic Response Group, all fired shots at Saheed Vassell in Crown Heights on April 4, according to police sources.

The 34-year-old Vassell — whose family said he suffered from bi-polar disorder — could be seen on surveillance video terrorizing people with a pipe-like gun.

A total of 10 shots were fired and Vassell was struck several times. He was taken to the hospital, where he died.

Sources said that Bottiglieri and Molic are white males, while Dingham is African American. Rafiq is of Middle Eastern descent.

They have between 4 and 7 years on the job.

None of the four officers have prior incidents of discharging a firearm.

The incident sparked protests and a debate over whether police should have opened fire on the mentally disturbed man.

The names of the officers were shared with an attorney for the family of Vassell.
