Twenty people were arrested after crowds clashed with police during street parties following the Puerto Rican Festival.

The number of arrests kept growing overnight as things got out of control during what has become an all too familiar scene of chaos around the same event every year. Things got so bad as hundreds started leaving the festival.

Police dressed in riot gear responded to the northeast side of the city to get everyone to go home. Authorities say some in the crowd started throwing bottles and rocks at officers. The fire department also responded to put out garbage fires on city streets. State Police brought in their helicopter to keep watch overhead.

At one point, some people started trying to get into a News10NBC vehicle as crews drove down the road.

At the same time, another scene started to unfold near Clifford Avenue and Thomas Street. Police responded to reports of a shooting about 10:30 p.m.

A 28-year-old man who had been shot at least once walked into the hospital after being dropped off. The victim went into surgery and is in stable condition. No arrests have been made in that case. There's been no update on how or even if that shooting may be tied to what was happening in other parts of the city.

The 20 people arrested following the Puerto Rican Festival are due in court at 9:30 Monday morning on charges ranging from DWI and other traffic-related offenses to assault and child abuse charges.
