Cops review new security camera video of man who appears to be Ahmaud Arbery walking into a construction site and running off just minutes before he was shot - as armed Black Panthers protest in neighborhood where he was killed

The Georgia Bureau of Investigation has confirmed it is investigating additional video footage in the Ahmaud Arbery case. 

Arbery, 25, was out jogging in Brunswick on February 23, before he was shot dead by father and son Gregory and Travis McMichael, who had trailed him in a white pick-up truck. 

The new video, which appears to have been taken by a home security camera shortly before the shooting, shows a man believed to be Arbery entering into the garage of a property under construction.

The clip, obtained by The Atlanta Journal-Constitution, shows the man at the construction site for less than five minutes before he appears to leave via the front door with nothing. 

The McMichaels have claimed they followed Arbery in their pick-up truck because they believed he was a burglary suspect. 

But while the new video could complicate the narrative that Arbery was simply out jogging in the neighborhood, prosecutor Manny Arora told the Atlanta Journal-Constiution that entry onto a construction site is not necessarily a crime if nothing is stolen.  

Arbery's family lawyer, Lee Merritt, told CNN that that incident would be classified as 'trespassing at most'. 

Meanwhile, heavily-armed protesters from the Black Panther Party, 'I Fight For My People', and 'My Vote is Hip Hop' gathered Saturday to demonstrate in the Satilla Shores neighborhood near where Arbery was killed.

A vigil was also held Saturday in Sidney Lanier Park in Brunswick, a day after what would have been Arbery's 26th birthday. It was attended by friends and family including Arbery's mother and sister and featured live music, a balloon release and memories of Arbery.

Arbery's death has sparked nationwide outrage. A rally for the slain jogger was held Friday - the day he would have celebrated his 26th birthday 

The new security footage which has emerged begins with the man, believed to be Arbery, walking into the garage of the under-construction house. 

He then re-emerges seconds later and walks around the side of the property. 

Soon after, a neighbor can be seen standing across the street observing the scene.

Less than five minutes later, the man believed to be Arbery leaves through the front door of the under-construction house, before running off in the direction of Travis McMichael's home.

At the far edge of the screen, two people can be seen around a parked truck. It is not clear whether the vehicle is in the driveway of Travis' home or near it.

The truck can be seen taking off in the same direction the man believed to be Arbery had run, according to The Atlanta Journal-Constitution. 

The publication also reports that a 911 call was made around the same time to report that there was someone loitering around the under-construction property. 

The 911 dispatcher on the other end of the phone reportedly stated: 'You said someone is breaking into it right now?

'No,' the caller replied.  'It's all open, it's under construction. And he's running right now! There he goes right now... He's running down the street.' 

In a statement released Saturday, the GBI said that they are investigating the security camera footage.

The statement said: 'There are reports circulating of additional video footage being reviewed by the GBI as a part of the Ahmaud Arbery murder investigation. 

'We are indeed reviewing additional video footage and photographs as part of the active case. 

'It is important to note that this footage was reviewed at the beginning of the GBI investigation and before the arrests of Gregory and Travis McMichael.'
