Police made 74 arrests in Rochester, New York, during a protest over the shooting of black residents across the nation.
The Rochester Democrat & Chronicle said the arrests occurred late Friday night and early Saturday morning.
Police say the arrests were for disorderly conduct.
Demonstrators on Friday protested the fatal shooting of black men by police in Louisiana and Minnesota and also the deaths of some local residents this year.
No police officers were injured and there was no property damage reported.
Police told protesters they were blocking the streets. Ashley Gantt, one of the protest organizers, says people sat on the ground when a SWAT team arrived because they did not want to appear aggressive.
Gantt urged those being arrested to remain calm.
Two reporters were briefly detained.
