On Monday, authorities arrested nine adults and two juveniles who were involved in a high school and college drug ring located in an affluent suburb of Philadelphia. 

Prosecutors say that two former students of an elite private high school started the drug ring to control the marijuana trade at local high schools and colleges within a corridor of towns known as the Main Line. Hence, they named the operation the "Main Line Take Over Project."

The alleged ringleaders, 25-year-old Neil Scott and 28-year-old Timothy Brooks, both graduated from the prestigious Haverford School. They employed other affluent prep school students and graduates to work as "sub-dealers," selling marijuana, cocaine, hash oil and MDMA to student, according to the New York Times.

In response to the allegations, officials from The Haverford School sent out a letter to the school community, written by headmaster John A. Nagl, stating: "The Haverford School obviously does not tolerate such activities and is cooperating with authorities. We are committed to maintaining a drug-free learning environment at The Haverford School."

Nagl also told MainLineMediaNews.com that  "These are serious allegations ... we are shocked and horrified and are working hard to prevent anything like this from happening again."

Nagl pointed out that the availability of marijuana has increased now that some states have loosened laws regarding the sale of the drug. As a result, Scott used his experience working at medical marijuana dispensary in California to funnel marijuana to his apartment in Haverford, his parents' home and to Brooks' home in Villanova. 

"This was not a game. These people were in business, they were in business to make money and they were going to do whatever they needed to do so that no one threatened their business," Montgomery County DA Risa Ferman told NBC News.

Ferman added that, "The high school sub-dealers were encouraged to develop their business so that they could sell at least one pound of marijuana each week. Brooks instructed the dealers to make sure that there was never a drought."

Scott is being held on $1 million bail, but Brooks was released after his parents posted the $25,000 bail.
