SAN FRANCISCO - San Francisco police held their required town-hall meeting after SFPD fatally shot and killed a man at San Francisco International Airport who allegedly brandished replica guns.

Police released video from the Jan. 20 incident, including police-worn, body-camera footage. The shooting of Nelson Szeto, 37, is being investigated by California State Attorney General Rob Bonta's office. Police are characterizing the event as a 'suicide by cop.'

At Monday's virtual presentation, SFPD Commander Paul Yep said, "At one point, Mr. Szeto told officers to shoot him." Yep continued to say Szeto said things like, "center mass," adding, "make sure you aim," and also, "Thank you for your service. I respect you guys." Yep said Szeto also apologized, stating several times that he was sorry.

Yep said officers reiterated that they did not want to shoot the man. Crisis negotiators worked to deescalate the situation. Police also used less than lethal ammunition before firing live rounds.

SFPD were initially called for reports of a man who was acting erratically just outside the international terminal's BART entrance.

Before the shooting, Szeto allegedly pulled out what appeared to be a real gun and a knife. The guns ended up being airsoft guns, which fire plastic pellets. These type of replica firearms normally have orange tips, but in this case they did not.

The department said Szeto had already placed one airsoft gun and the knife down when he was shot and killed by SFPD officers. Police said four officers opened fire when he raised one of those guns towards officers. Police show various angles from the incident.

Police have identified the involved SFPD officers as officers Erik Whitney, Oliver Lim, Steven Uang, and David Wakayama.

CHICAGO (WLS) -- Three men are charged after a shootout with Chicago police that left one of them critically injured Wednesday night.

Chicago police said officers were attempting to stop a car that had been taken in a carjacking with three men inside. After pulling the car over, as officers approached the vehicle, there was an exchange of gunfire, according to CPD.

Edgardo Perez, 24, was shot by police and taken to Northwestern Memorial Hospital in critical but stable condition. He is now charged with attempted first degree murder of a Chicago police officer.

The two other people in the car were taken into custody. Jesse Sanchez, 21, and Noel Centeno, 20, are also now facing felony charges for alleged possession of a stolen vehicle and weapons charges.

Two weapons were recovered, police said, a pistol with a laser sight and a revolver.

Video obtained by the ABC7 I-Team from law enforcement sources shows the dramatic confrontation as it happened when Chicago police shot a man in the heart of downtown Wednesday night.

The shooting happened around 8:45 p.m. near Lower Wacker Drive and Columbus Drive, an area which is heavily traveled both ways near the Chicago River.

No officers were shot, but a 34-year-old officer and a 30-year-old officer were taken to local hospitals to be treated for minor injuries, according to police.

The age and gender of the people in custody have not been released.

The scene cleared about 4:30 a.m. Thursday, and a car riddled with bullet holes was towed away.

Video from a police POD cam shows the first officer come to the passenger-side window, then go down for cover, either seeing a gun or responding to suspect gunfire, before getting back up to help other officers.

The Civilian Office of Police Accountability said it was responding to the shooting.
