A video recorded on a witness's cell phone shows interaction between Vineland police officers and Phillip White, a 32-year-old man who died in police custody last week.

The video, which was provided to NBC10.com by a family friend of White according to the news outlet's website, shows White on his back on the ground while a police K-9 attacks him.

An officer screams at White to "roll over, put your hands behind you head! Do it now!"

Later, a police officer tells the person recording the arrest that he's "going to need to take your phone" and asks for the person's name.

After the arrest, White was taken to the hospital in "respiratory distress," according to the Cumberland County Prosecutor's Office. He became unresponsive en route to the hospital and was later pronounced dead at Inspira Medical Center Vineland.

The prosecutor's office is investigating the incident, which began on the 100 block of Grape Street in Vineland on Tuesday when officers were called out for a report of a disorderly person.

Witnesses have said that White was beaten by officers and bitten by the police dog.

Audio of police communications during the incident revealed that authorities said White was "hyperventilating" and one officer later said that White "tried disarming me," according to 6ABC.com.

White's family retained a lawyer last week to conduct an independent investigation into his death. The lawyer, Conrad Benedetto, is the same lawyer retained by the wife of Jerame Reid, a Bridgeton man who was shot and killed by police in December after a traffic stop in Bridgeton in which a gun was revealed.

"The public and Mr. White's family deserve answers as to how Phillip was killed and why there is a lack of oversight of local police," said Benedetto.

It was unclear Monday whether an autopsy on White had been conducted.

The prosecutor's office has asked anyone with information or video of the incident to contact Sgt. Scott Collins by calling 856-466-5127 or SAC E. Ronald Cuff by calling 609-381-4890.
