Ariana Grande brought the city of Manchester together on Sunday night for an emotional benefit concert in efforts to raise money for the victims and their families affected by the Manchester bombing last month.

One Love Manchester was an absolute success, garnering $9 million for the British Red Cross. And while performers like Miley Cyrus, Coldplay and Pharrell Williams contributed to the monumental concert, there is one moment that instantly went viral on social media.

As Justin Bieber closed out his set, cameras captured a group of people dancing outside with a police officer who also joined in helping pay tribute to the victims. The video shows the officer dancing around while holding hands with mourning concert goers.

On May 22, while Grande was wrapping up her concert at the Manchester Arena, a bomb went off inside the venue’s foyer. The tragic incident, which was ruled a terrorist attack, killed 22 people and injured 59 others.
