Four people are under arrest for their alleged roles in a large-scale heroin distribution ring in the Reading area, according to state Attorney General Kathleen Kane.

A grand jury has identified 29-year-old Eliud "Drop" Price of Reading as a "high-level distributor of bulk heroin" in the Reading area, according to the Attorney General.

Between November 2010 and August 2011, agents made a series of controlled purchases from Price, according to the Attorney General. Over the course of the investigation, agents said they seized or purchased approximately 81 grams of loose heroin from Price, which has an estimated street value of at least $40,000.

According to the grand jury, Price was assisted in his drug enterprise by three associates: 34-year-old Bryan Rice of Reading, 31-year-old Edward Woods of Reading and 24-year-old Kimber Griffiths of Hughesville, Lycoming County.

As the investigation progressed, agents learned that these associates also sold cocaine, ecstasy, and marijuana, according to the Attorney General.

Rice and Woods were taken into custody Tuesday, and are being held on $750,000 bail.

Price and Griffiths remain at-large.

Anyone with information regarding their whereabouts is asked to contact Berks County Communications at 610-655-4911.

Authorities say the investigation is continuing.
