New York Governor Andrew Cuomo on Monday called for a national ban on excessive force by police and announced a curfew for New York City following violent protests triggered by the death in Minneapolis of an unarmed black man in police custody.

In a joint statement, Cuomo and New York City Mayor Bill de Blasio said the city of eight million people would be under curfew from 11 p.m. local time on Monday night until 5 a.m. the next morning. 

They said the police would double their numbers to stem violence and property damage.
