Police believe an altercation at a block party may have led to the stabbings.

An eyewitness told FOX 29 it was a large group of mostly "young people" who squared-off into fights on the street and on the sidewalk along the block. 

Police say the attackers were using equipment left behind from an earlier festival on the street to attack their victims. 

"Some of the items left on the street such as a canopy were used in the attack. It was a very serious matter we are still looking for 2 suspects involved in that fight," said Inspector D.F. Pace.

No arrests have been made as police canvas surveillance footage in the area.
