Using the hashtag #roomformanchester, social media users offered lodging, food and additional support for individuals affected by the tragedy.
One woman who gave support in wake of the tragedy was Paula Robinson. The 48-year-old said she took dozens of girls to a nearby hotel and posted her phone number on social media, telling worried parents to meet her there, according to Reuters.
Reports say Grande's mother, Joan, was in the front row at the concert and helped escort young fans backstage to safety.
The Manchester Evening News started a fund to help support families in the aftermath of the attack.
"Parents were frantic running about trying to get to their children," Robinson told Reuters. "There were lots of children at Holiday Inn."
