Ten arrests were made for drug possession, 25 for being a person under age 21 in possession of alcohol, three for disorderly conduct, one for domestic assault and battery, and five for possession of a forged license. Alex Marotte, 21, of Springfield was arrested and charged with posession of ecstasy with intent to distribute.

“Police and emergency medical services were extraordinarily busy throughout the day and evening with criminal activity and medical issues. ... These matters continue to be actively investigated by Mansfield Police Department detectives,” said O’Neill.

The “Identity Tour” was a “rave” concert that offered several performance stages and techno music, police said.

Brandon and Impelizzieri were initially treated at Sturdy before being transferred to Boston Medical Center and Rhode Island Hospital. Police learned this morning of Brandon’s death.

Impelizzieri was revived from full cardiac arrest by emergency workers posted at the concert, but later succumbed to substances he had ingested, the statement said.
