Disturbing footage captured the moment a man in Maine drove slowly in circles during a deadly shooting by Immigration and Customs Enforcement (ICE) agents after he allegedly accelerated his car at them.

The unidentified motorist was killed in the town of Biddeford shortly after 7am ET Monday morning after apparently ignoring orders from officers.

Footage from the scene showed the victim's white Kia driving slowly in circles at an intersection, as an ICE agent runs alongside the vehicle. 

It is unclear if the footage was taken before or after the driver was shot, with lawmakers calling for urgent answers as to what ICE was doing in the small Maine town or why the vehicle was targeted. 

Separate Ring camera footage obtained from inside a nearby home by The Maine Wire captured the sound of the deadly confrontation, as a barrage of around five shots were fired rapidly. 

Photos taken in the aftermath showed a bullet hole on the windshield of the white Kia sedan being driven by the victim when he was killed.

A witness told the Portland Press-Herald that the man emerged from the car bleeding profusely from his head moments after the shooting.

Photos taken from the scene show the victim lying on a nearby road, as ICE agents and police consoled each other. 

It remains unclear if the victim happened upon ICE by chance or if he was protesting the presence of officers. 

Agents have been carrying out raids in Biddeford in recent weeks and locals knew they were there, the Press-Herald reported. 

Maine's House Speaker Ryan Fecteau said he was waiting to hear details over what led to the deadly shooting, saying in a short statement: 'A person was killed. ​ICE was involved.

'State Police and the Department of Public ​Safety are now on scene to gather details and would expect the FBI to investigate as well. These are the details that I have at this time. I will provide further updates, as they are relayed to me.' 

Witness Lucas Scott, 18, told the Press Herald that he was driving through the intersection moments before the shooting, and saw a group of unmarked vehicles descend on another car. 

He said he saw agents in ICE uniforms confronting the driver of the vehicle, seconds before an agent pulled his weapon and ordered the man to exit his car.

'The car was put into drive and was trying to hit the ICE officer,' Scott said. He said he then heard the ICE agent fire several shots quickly. 

A spokesman for Biddeford Police told CNN that there was no further threat to the public.

Mary Hayes, a resident who lives near the scene, told the Press Herald that she did not see the agent open fire, but arrived in time to see the victim lying in the street. 

'There's a dead body down there,' she said. 

'I mean, we live in Maine. We don’t expect this to happen here. What have we come to?' she added. 

Maine Congresswoman Chellie Pingree said she was 'deeply disturbed and angry' by the news. 

'I, of course, need to know all of the answers here,' the Democrat said. 

Pingree said she wanted to know if the ICE agents were pursuing a migrant with a criminal record or if the shooting was a routine traffic stop, but added, 'More than anything else, I want to know why you're in Maine?'

'Every report we hear is about somebody being picked up who legally was here, and is this going to be another one of those stories?'  

It comes just days after an ICE agent fatally shot a Mexican immigrant during a traffic stop in Houston, which sparked mass protests. 

Scrutiny on ICE activities was also compounded by the fatal shootings of anti-ICE protesters Alex Pretti and Renee Good in Minnesota earlier this year. 

The shooting on Monday has quickly led to calls for protest, with the social justice group Biddeford Saco for Racial Justice saying on Facebook that it would be holding a demonstration within a matter of hours. 

'Folks are really upset,' the group said. 'I imagine there will be more.'
