PORTLAND, Ore. (CBS/AP) -- A touching photo of a white police officer hugging an African-American boy at a Portland protest this week has drawn heavy attention on social media.

The moment was captured by photographer Johnny Nguyen covering a protest in Portland, Oregon, over a Missouri grand jury's decision not to indict Ferguson police officer Darren Wilson for the shooting of Michael Brown.

At the Portland rally was 12-year-old Devonte Hart, who stood crying out of sadness over the events in Ferguson. He was holding a "Free Hugs" sign.

Portland Police Sgt. Bret Barnum saw the boy's sign and asked if he could have a hug. The boy gave him one.

Devonte's mom Jen Hart was there Tuesday and remembers the moment as "one of the most emotionally charged experiences I've had as a mother."
