Police in Connecticut have arrested a fifth Wesleyan University student on drug charges stemming from on-campus overdoses that sent a dozen people to the hospital.

Middletown police say 21-year-old Abhimanyu Janamanchi of Rockville, Maryland, turned himself in on an outstanding warrant Friday morning. He faces charges including distribution of a hallucinogen and is being held on a $50,000 bond. The Associated Press could not immediately determine whether he has an attorney.

Four other students already have been arraigned on charges related to overdoses on the club drug Molly that occurred the weekend of Feb. 22.

The overdoses left two students in critical condition, but the family of the last patient in the hospital said last week that the student would survive.
