AUGUSTA — A Manhattan man was ordered to serve 23 months in prison Tuesday for unlawful trafficking in cocaine base.

Tymell R. Waters, 31, pleaded guilty to the charge at the Capital Judicial Center. A second charge, aggravated trafficking in heroin, was dismissed in exchange for that plea.

Waters was one of seven people arrested Nov. 2, 2013, in a drug bust at two locations: an apartment on Gage Street and a room at the Senator Inn & Spa on Western Avenue.

The raid followed an investigation of several months into the sale and distribution of heroin and crack cocaine, according to an affidavit filed in court by Brian Wastella, an Augusta police officer working with the Maine Drug Enforcement Agency.

At the time, Deputy Chief Jared Mills, of the Augusta police, said the bust was “one of the most significant” in the recent past.

“We believe this was a large supplier within our area,” Mills said.

Waters was found with five other people inside a hotel room, and agents reported seizing a solid white substance later determined to be 108 grams of crack cocaine, 66 grams of a substance suspected to be heroin, and a half-pound of marijuana, as well as two firearms.

One of the others arrested with Waters, Frederick Rogers, 32, of Queens, New York, pleaded guilty earlier this month to a charge of unlawful trafficking in cocaine and was sentenced to two years in prison.
