No arrests were made during the Women's March on Washington Saturday, according to a top official in the capital.

The peaceful protest, which had an estimated 500,000 in attendance, was so much larger than its expected size that the march route had to be altered and couldn't pass the White House as planned.

D.C. Homeland Security Director Christopher Geldart told NBC news that despite the massive crowds, no arrests were made. On Friday after the inauguration, protests led to the arrests of more than 200 people and the use of pepper spray and stun grenades by police.
