More than a ton of marijuana and $1 million in cash were seized the Anne Arundel County yesterday as part of a coordinated crack-down on East Coast drug sales that began Thursday in Flordia with the seizure of 40 tons of marijuana valued at $31 million, Maryland police officials reported.

Nine persons were arrested yesterday in Maryland, and seven Thursday in Florida, police said.

The combined effort of Maryland, Flordia, and federal officials marks one of the largest drug cases in East Coast history, according to a spokesman for the federal Drug Enforcemen Agency.

Officials said they believed the Maryland area was the distribution center for the drug ring which operated between Pennsylvania and Florida.More arrests are expected, police said.

The investigation began last Jan. 6 when Baltimore County police learned from a "confidential informant" that $112,000 in cash from previous drug sales had been hidden in a are in northern Baltimore County, according to Lt. Kenneth West, a Baltimore County police investigator.

The cash was seized, and court-approved wiretaps were begun on several suspects, which led to the recent arrests, West said.

Drug raids Thursday in Maine, in which marijuana valued at $16 million was seixed and 31 people arrested are not believed connected to the Maryland operation, West said.
