Montgomery County police arrested 14 persons and seized nearly 100 pounds of marijuana in a raid Thursday night on three Silver Spring apartments, police said.

The police raid capped a two-month investigation of residents in garden apartments at 8802, 8810 and 8818 Lanier Dr., Officer Herbert C. Cahalen said.

Three police teams armed with machine guns and rifles entered the apartments at 9 p.m., and seized $13,000 in cash and marijuana with an estimated street value of $251,000, Cahalen said. Also seized were a video cassette recorder, a radio and other appliances believed stolen from homes elsewhere in Montgomery, police said.

Police arrested Veronica Kelly, a 27-year-old Jamaican national, and her husband, Earl, 28, of 8810 Lanier Dr., Cahalen said. The Kellys, who police alleged were leaders of a marijuana-selling ring, were charged with possession of marijuana, possession with intent to distribute, conspiracy and two counts each of felony theft, Cahalen said.

They were being held yesterday at the county detention center in lieu of $40,000 bond each, police said.

Cahalen said that most of those arrested Thursday were Jamaican natives, and that several of them were members of a Rastafarian sect who smoke marijuana as part of their religion.

The 12 people arrested with the Kellys also were charged with possession of marijuana and possession with intent to distribute, police said.

Police said that they were identified as Lonnie Miller, 35; Keith Deans, 29; Dan Moore, 20; Ian Fox, 24; Earl Fuller, 28; Derrick Black, 25; Keith Brown, 34; Tyrone McCleary, 27; Derval Fallen, 27; Clifton Bennett, 22; Calvin James, 25, and Jerome Lightfoot, 36.

The 12 were held yesterday in lieu of $5,000 bond each, police said.
