NEW LONDON, Conn. (AP) Firefighters in New London saved two lives over the weekend by administering the opioid reversal drug Narcan to suspected heroin overdose victims.

Fire Chief Henry Kydd says the department's ambulances responded to two separate calls Saturday regarding one semi-conscious victim and another unconscious victim.

The Day reports firefighters completed training on how to administer Narcan at the end of February.

Firefighters, police and emergency medical technicians have been training with Narcan since a state law was passed to diminish the civil or criminal liability of its administration.

Kydd says every ambulance and fire engine carries the medicine and crews have used it more than a half-dozen times.

The number of heroin-related overdose deaths in Connecticut increased by more than 86 percent between 2012 and 2014.
