NEW LONDON, Conn. (AP) Officials say at least three more people have been treated for suspected heroin overdoses in New London days after the city held a vigil calling attention to a spate of overdoses in recent weeks.

New London Battalion Chief Keith Nichols says emergency responders treated two male patients Saturday afternoon. A woman was treated about an hour later. All three were taken to an area hospital.

The overdoses come weeks after hospital officials reported an ``unprecedented'' number of heroin overdoses, with more than 20 cases between Jan. 27 and Feb. 5.

Officials had attributed the uptick to a potentially lethal supply of heroin.

The Day reports that two people died of suspected heroin overdoses in the city during the same period.

A vigil was held for the overdose victims on Thursday.
