SANTA CRUZ (KRON) — Six students at the University of California at Santa Cruz have been arrested on Friday for allegedly running a drug ring that uncovered over $100,000 worth of MDMA, according to Santa Cruz police spokeswoman Joyce Blaschke.

Police said the students were affiliated with one of the two affiliated campus Greek organizations, Alpha Kappa Delta Phi and Lambda Phi Epsilon.

The suspects were identified as Mariah Dremel, Benny Liu, Cesar Casil, Nathan Tieu, Hoai Nguyen, and Cecilia Le, all 21 years old, who allegedly possessed a controlled substance, police said

Dremel, Liu, Casil and Tieu are also suspected of conspiracy, according to police.

About 5,000 tablets of MDMA that weighed about 4.1 pounds were found and have a street value of more than $100,000, police said.

Police worked on the case with help from personnel at the Department of Homeland Security and U.S. Postal Inspection Service.

Officers learned that multiple packages containing MDMA tablets were being sent through the U.S. Postal Service over the past few weeks to three Santa Cruz addresses, where search warrants were served on Friday, police said.

The homes were in the 400 block of Locust Street, 200 block of Castillion Terrace and the 100 block of Peach Terrace, according to police.

The warrants were served with help from the Santa Cruz County Anti-Crime Team, Drug Enforcement Administration, U.S. Postal Service and Homeland Security, according to police.

Officers learned on Friday that Homeland Security investigators were able to stop a second shipment from arriving to the group, police said.

MDMA, more commonly known as Ecstasy or Molly, is a psychoactive drug that can increase a person’s heart rate and blood pressure, DEA officials said.

People can experience increased energy from the drug in addition to sadness, anxiety and depression, according to DEA officials.

If taken in large doses, MDMA can lead to serious health complications or death, DEA officials said.

Lambda Phi Epsilon is described as an international Asian-American-interest fraternity that sets high standards for academics, social experience and community service, according to the college’s website.

Alpha Kappa Delta Phi sorority’s Delta Chapter was created 24 years ago and aimed at advancing sisterhood, philanthropy, scholastic excellence and Asian-awareness in the community, according to the group’s website.Bay City News contributed to this report
