Six months after the G20 Summit, an officer has been charged with assaulting a protester at Queen’s Park.

Working with evidence supplied in part by the Toronto Star, Special Investigations Unit director Ian Scott said in a news release Tuesday: “There are reasonable grounds to believe that an officer... committed a criminal offence in connection with the arrest of Adam Nobody on June 26.”

Constable Babak Andalib-Goortani has been charged with assault with a weapon.

Andalib-Goortani is the previously unidentified officer whose image ran on the Star’s front page just two weeks ago.

On Dec. 7, the newspaper ran a story about newly obtained video footage showing the officer’s face peering through a raised visor after he appeared to wield his baton during the takedown of Nobody.

On Dec. 8, a picture was published of the same officer participating in the takedown of National Post photographer Colin O’Connor. Two officers in the immediate vicinity — J. McIntyre and S. Ma — were identified through pictures with their name tags on.

The arrest comes less than a month after the SIU concluded its investigation into Nobody’s injuries, as well as five other cases. While the police watchdog said excessive force was probably used in Nobody’s case, it was impossible to identify the officer. Scott pointed to a YouTube video titled “Toronto G20, Peaceful Protestor Tackled and Roughed Up.”

Police Chief Bill Blair lashed out in a radio interview, saying the video of the 27-year-old stage builder was “significantly tampered with and fabricated.” He suggested police were in the middle of arresting a violent armed offender.

John Bridge, who shot the video, signed an affidavit saying there was a four-second gap in the video because he briefly switched off his camera when he saw police rushing toward him.

Blair later apologized to Nobody.

The chief’s claim unleashed a flood of citizens’ evidence of the volatile demonstrations during the summit of world leaders that turned downtown Toronto into an armed camp.

On Nov. 30, the SIU reopened Nobody’s case, and then released photographs of two bystanders recording his arrest and asked for their help. At least one came forward.

The Star later provided a second video.

Toronto police gave the SIU the names of 15 officers who may have been in the area or had something to do with Nobody’s injuries.

“Through an analysis of the video imagery and additional information gathered during the reopened investigation, SIU investigators determined that three of the named 15 officers may have caused injuries to Mr. Nobody related to his first allegation of assault,” Scott said.

“Twelve officers were designated as witness officers and interviewed,” but none could identify themselves or any other officers in the videos, Scott said.

The three subject officers declined to provide a statement “as is their right,” he said.

Police then gave the SIU the name of a 16th officer who identified one of the subject officers as Andalib-Goortani, said Scott.

When asked whether Nobody’s case is closed, SIU spokesman Frank Phillips said: “At this point, yes. But this time is the same as the last time. If we get new material evidence... then the investigation could be reopened.”

Lawyer Sunil Mathai, who’s representing Nobody, said he was encouraged that at least one officer was being held accountable, but added: “It is regrettable that 12 witness officers were unable to identify themselves or others in the video... This makes a mockery of the duty to cooperate.”

Toronto police had little to say after the SIU statement.

“It’s an ongoing SIU investigation,” said Constable Tony Vella. “We cannot make any comments on ongoing SIU investigations.”

Police union president Mike McCormack kept his comments brief, “unlike Mr. Scott’s fulsome and lengthy media release.”

“The proper forum for this matter is in the courts and not in the media,” he said.

“Our members should be judged on the facts, not just a one-sided story.”

McCormack added the union fully supports Andalib-Goortani.

“I’m grateful that they finally have someone who’s going to stand before a court,” Nobody said Tuesday night. “It’s not something (that can be swept) under the rug.”

Nobody claims that after he was roughed up at Queen’s Park, he was handcuffed, taken behind a police van and kicked repeatedly in the head by two plainclothes officers. He said he was disappointed there are still no answers in his second allegation.

“I would definitely like to see those two brought to justice,” he said.

“A lot of things happened that day and one happened to be on video and that’s why they’re still talking about it.”

Andalib-Goortani is scheduled to appear in court Jan. 24.

According to officers at 31 Division, a Babak Goortani — who one officer referred to as “Bob” — works with the traffic division and was on the 7 a.m. shift Tuesday.

There was no answer at a Richmond Hill condominium under his name.

“The SIU would like to thank videographer John Bridge for coming forward and sharing both the manner in which he shot his video, permitting himself to be identified and providing the unit with his original video footage of the incident,” Scott said.

“The media and other members of the public also played a pivotal role in assisting the investigation.”

The SIU investigates incidents involving police that result in death, serious injury or allegations of sexual assault.
