BRISTOL, PA. – Another arrest has been made in connection with illegal drive-by gatherings last month in Philadelphia.

Police said Joseph Cavenaugh, 21, of Bucks County, was a key organizer in planning the illegal meetings.

FOX 29 cameras were on scene as police arrested Cavenaugh at his Bristol home Friday morning for his role in the Sept. 21 mayhem across the city.

Philadelphia police say they’re not done arresting people and are urging people not to return to Philadelphia to do it again.

Lt. Dennis Rosenbaum of the Philadelphia Police Department issued this warning to those who might be tempted to come to Philadelphia to wreak havoc: “There will be consequences. If you come to Philadelphia now, we’re not going to tolerate it. “You have a lot of investigative resources on this and, as I said before, you will see us coming knocking on your door first thing tomorrow morning.”

The arrest comes two weeks after police arrested Shane Thomas, 18, for his role in the illegal car encounters.

Investigators say Thomas was seen on video throwing a cone at police while wearing a fanny pack suit.
