MDEA agents seized nearly three pounds of cocaine and heroin/fentanyl and arrested three Massachusetts men and a local man Tuesday in Sanford, police said.

Drug agents seized a handgun, a sawed-off shotgun and more than $35,000 dollars in suspected drug proceeds during a search of Nathan Frechette’s Nason Street home Tuesday afternoon, Stephen McCausland, spokesman for the Maine Department of Public Safety, said in a Wednesday news release.

Frechette, 39, was arrested without incident and charged with aggravated trafficking of a scheduled drug. Following his arrest, he was taken to the York County Jail.

Yarlin Garcia, 24, and Pedro Igyedi, 21, both of Lowell, Massachusetts, were arrested along with Luis Rosario-Diaz, 21, of Lawrence, Massachusetts after driving to Frechette’s home from Lowell. After the men arrived at the home, drug agents found 1 1/4 pounds of cocaine and more than 1 1/2 pounds of heroin/fentanyl hidden in the engine compartment of their rental vehicle, McCausland said.

All three Massachusetts men were charged with aggravated trafficking of a scheduled drug and taken to the York County Jail.

Police said the drugs, which had a street value of more than $140,000, were destined to be resold in York County and the greater Brunswick area.

The release said the Massachusetts men had been traveling to Maine to sell Frechette coke and heroin by the pound.

Police said additional charges will likely be filed after drug testing has been completed on the heroin.
