Heightened security is in place for a New York City music festival where two people, one an SU graduate, died last year.
Electric Zoo officials said Friday they're beefing up plainclothes security and using off-duty and former NYPD officers with a background in drug investigations.
Medical precautions also are being taken at this weekend's event.
Organizers will shorten the length of each day's show by two hours. And Electric Zoo will provide electrolytes for free.
The final day of last year's festival was called off after two people died from an overdose of MDMA combined with hyperthermia.
Ticket buyers will have to watch a 2-minute video about MDMA, also known as molly or ecstasy. The code to activate wristbands will be in the video.
The festival is being held Friday through Sunday on Randalls Island.
