New York mayor: Police will respect peaceful protest

Demonstrators turned out in New York City on Friday to protest the death of George Floyd.

Floyd died after an encounter with Minneapolis police on Monday.

Video of the incident went viral and has led to protests around the U.S. _ including incidents of looting in Minneapolis and St. Paul.

New York City police arrested more than 40 demonstrators Thursday evening after protests turned violent.

Mayor Bill de Blasio on Friday urged demonstrators to protest peacefully.

"Please, even if you're expressing that pain, that anger, that sense that something's wrong and must be fixed, please remember how important it is to protest peacefully," the mayor said
