Two people are under arrest, after a large crowd threw bottles at RPD officers.
Police say it happened late last night on North Clinton Avenue, ranging from Upper Falls Boulevard to Avenue D.
It took hours to break things up, but there was another mass gathering a few blocks over at Morill and Remington streets.
A couple of people there fired several shots, hitting a nearby car and home.
No one was hit by the gunfire.
So far, there are no arrests related to the gunfire.
