Shocking surveillance video has been leaked on social media showing the fatal shooting of Chicago mother Brittany Hill who was shielding her toddler daughter from gunfire.

Chicago police spokesman Anthony Guglielmi released a statement Sunday night calling the video's release 'unauthorized.'

Guglielmi said that police have notified the Cook County State's Attorney's Office about the video and that the department is working to determine how the video was accessed.

Two suspects, identified as Eric Adams, 23, and Michael Washington, 39, were arrested on first-degree murder charges just hours after Hill's fatal shooting on May 28.

Surveillance video has been leaked on social media showing the fatal shooting of Brittany Hill, 24, who was shielding her one-year-old daughter from the bullets

The recording came from a city surveillance camera on Chicago's West Side on May 28. The Chicago Police Department called its release 'unauthorized'

WBBM-TV reported the video came from a city surveillance camera on Chicago's West Side.

Two versions of the video - a longer and a shorter one - have made their way to Twitter, Instagram and YouTube over the past 24 hours.

DailyMail.com is showing only a portion of the video before shots are fired.

The leaked footage shows Hill standing next to a row of parked cars with her one-year-old daughter in her arms alongside two men.

A silver Chevy Impala drives by and someone inside opens fire, sending Hill and the two men running for cover.

As Hill, who appears to be wounded, stumbles towards the back of a parked vehicle seeking to hide there with her child, two men emerge from the silver sedan with guns drawn and unleash a barrage of bullets.

The suspects then get back in the car and speed off, leaving the woman lying on top of her daughter in her desperate attempt to protect the child.

A few seconds later, one of the men who was seen standing next to Hill at the time of the shooting returns to the scene, jumps back in his parked car and takes off, leaving Hill for dead.

The mortally wounded mother stirs and attempts to sit up while clutching her daughter. At that moment, another vehicle pulls over.

Two men emerge, grab Hill by her arms and legs and carry her into the backseat to take her to a hospital.

The woman's baby daughter, who appears to be just learning how to walk, gets to her feet, takes a couple of unsure steps while looking around, then falls down.

An older man then walks over, scoops the toddler up in his arms and carries her away to safety as the car carrying the child's dying mother drives off.

Hill was pronounced dead at West Suburban Hospital a short time later.

The shooting is being investigated as a possible gang-related targeted attack against the people Hill was speaking with, but not against her.

The first shot struck Hill in the torso, police said, before she tried to get away from the gunshots by hiding behind a row of parked cars, police say.

The two suspects in the shooting, Adams and Washington, both from Urbana, appeared in court last Thursday and were denied bond.

Cook County judge John F. Lyke Jr called the shooting ;chilling, mind-boggling and utterly senseless.'

Prosecutors revealed in court that Hill's baby was waving at the vehicle the men were riding in before the shooting. The leaked video appears to confirm that.
