BETHEL WOODS, N.Y. - New York State Police say they've made several arrests and recovered various kinds of drugs at an outdoor electronic music festival.

Troopers say Saturday they recovered cocaine, MDMA, ketamine, ecstasy and marijuana Friday from cars passing through checkpoints at the Mysteryland Music Festival in Bethel Woods.

The music festival includes performances from artists such as Bob Moses, Kevin Castro, Space Jesus and Wild Dark.

Thousands of attendees ages 21 and over travel to the four-day concert which also serves as a campground.

Mysteryland organizers say on their website that possessing, selling and using drugs is forbidden.

An upstate New York man was charged last year in connection with the death of another man they say overdosed on MDMA at New York City's Electric Zoo music festival in 2013.
