Pal of NYU shove victim Amelia Lewis helped obtain viral video that got creep busted

These coeds stick together.

An NYU pal of Amelia Lewis, the college student randomly assaulted while walking to class this week, was herself attacked in the Big Apple earlier this year — and was the one who got her hands on the viral video that helped cops nab her friend’s alleged tormentor.

“When I got Amelia’s text, I was in class and felt sick,” student Summer Armstrong said during an exclusive interview with Sirius XM host Megyn Kelly on Wednesday. “This also happened to me once, and I was lucky enough to have footage.”

Armstrong said she was the victim in a similar attack in May, with her assailant still on the loose.

“My assailant was never caught, but I knew footage is key,” Armstrong told Kelly. “My first thought was, ‘We need the footage, and we need to catch this guy.'”
