Philly Flash Mob: 'Crowd Of Teens' Arrested After Swarming Penn Square In Philadelphia

Another flash mob has reportedly appeared at City Hall in Philadelphia. What was described as a large disturbance erupted at 15th and Chestnut Streets, on the west side of City Hall in Philadelphia. Numerous people have already been arrested. Police warn drivers to stay away from Penn Square as they exit Philadelphia for the afternoon commute. Philadelphia's City Hall is in the center of a traffic-filled square formed by the junction of Market Street, the main artery through the Center City, and Broad Street, which runs north to south throughout the entirety of Philadelphia.

KYW 3 is advising those in Philadelphia to avoid Penn Square and numerous blocks to the west, through 18th Street along Chestnut, Walnut and Market, which encompasses much of Philadelphia's business district. Though the Philadelphia Police Department has not classified his incident officially as a flash mob, it has all of the makings of another eruption of senseless downtown violence.

This is not the first example of a random congregation of youth acting uncouth in Philadelphia. Over the past few years, Mayor Michael Nutter, D-Phila., has had enough of these so-called flash mobs.

"Pull up your pants and buy a belt!" he admonished local youth during a press conference after a previous flash mob erupted on a hot summer day in 2011 along Market Street.

Nutter attributed the observed lack of maturity among a number of participants in flash mobs to the fact their persona does not, in his view, lead businesses to want to hire them; something that he believes would make better use of their time than felonious lawbreaking and disrupting commerce.

"If you walk in somebody's office with your hair uncombed and the pick in the back and your shoes untied and your pants half down ... and you're wondering why somebody won't hire you? They don't hire you because you look like you're crazy!" Nutter said at the 2011 press conference.

Mayor Nutter later instituted a curfew law on youth after numerous random attacks on bystanders near the city's hospitals in the Society Hill neighborhood near Old City Philadelphia. He called out the parents of those involved in earlier mobs, saying they should be more responsible in raising their children and not be a "human ATM" for their teenage desires.

Following the Phillies World Series win in 2008, SEPTA, the city's mass transit provider, was forced to shut down service throughout South Philadelphia after violence erupted on Broad Street and hundreds of fans jumped in their cars to form a boundless impromptu victory parade along Oregon Avenue and South Broad Street. Robinson Luggage at S. Broad and Chestnut was allegedly broken into, and hundreds of Philadelphians sprinted down North Broad Street to City Hall, from as far as Temple University: a distance of nearly 3 miles. Graveyard shift commuters and innocent travelers were trapped in the Point Breeze and in the area surrounding Moyamensing Avenue as buses were unable to cross Oregon or Broad, and subway service had ended for the evening.

Police have yet not released any more specifics on Tuesday's impromptu fight in Philadelphia.
