Hispanic parade ends with crowd chaos in Wilmington, Delaware

E VINE STREET EXPRESSWAY AND THE SCHUYLKILL EXPRESSWAY. ALYANA. >> ALL RIGHT, ALYSSA, THANK YOU. WE ARE STILL WAITING TO HEAR FROM AUTHORITIES IN DELAWARE TO FIND OUT WHAT CAUSED A CULTURAL CELEBRATION TO DEVOLVE INTO CHAOS. NOW, THOUSANDS OF PEOPLE WERE GATHERED IN WILMINGTON YESTERDAY FOR THE CITY'S ANNUAL HISPANIC HERITAGE PARADE AND FESTIVAL. THE EVENT ITSELF WAS PEACEFUL, BUT THINGS TOOK A TURN AFTER THE FESTIVITIES WRAPPED UP. AS YOU SEE THERE, A HEAVY POLICE PRESENCE. THE ACTION CAM WAS THERE AS DOZENS OF POLICE CARS SWARMED THE AREA NEAR DUPONT AND FOURTH STREETS. TENSIONS ESCALATED AS OFFICERS WERE DISPERSING CROWDS. SOME PEOPLE WERE SEEN RUNNING AWAY FROM THE AREA. VIEWER CELL PHONE VIDEO CAPTURED WHAT APPEARED TO BE TENSE MOMENTS WITH POLICE. YOU SEE THERE A LINE OF POLICE CARS AND LIGHTS AND SIRENS. AUTHORITIES CALLED FOR BACKUP AND USED TEAR GAS TO CLEAR THE CROWD. THAT'S PROBABLY WHY YOU SAW SO MANY PEOPLE RUNNING, EVEN A WOMAN WITH A STROLLER. WITNESSES TELL ACTION NEWS THAT THINGS QUICKLY SPIRALED OUT OF CONTROL. >> THE GUY WAS ON DIRT BIKES DOWN THERE. THEY'RE DOING DONUTS OR WHATEVER. AND NEXT THING YOU KNOW, PEOPLE JUST STARTED THROWING BOTTLES AT THEM. AND IT WAS CRAZY. IT WAS REALLY CRAZY. IT WAS TERRIBLE. AND THEN THEY BROUGHT THE SWAT PEOPLE OUT. >> WHEN THE PARADE ENDS, EVERYBODY GOES THEIR OWN DIRECTION. BUT LIKE, THERE'S A LOT OF CARS THAT HANG OUT AND EVERYTHING, IT HAPPENS EVERY YEAR. THIS I'VE NEVER BEEN AROUND. AND IT HAPPENED LIKE THIS. >> THE PARADE AND FESTIVAL MARKED THE START OF HISPANIC HERITAGE MONTH, WHICH OFFICIALLY BEGINS TODAY. WE'VE REACHED OUT TO WILMINGTON POLICE
