ATLANTIC CITY -- Police have seized nearly a half million dollars in drugs and charged 41 men and woman in what authorities called a "significant" drug trafficking ring in the Atlantic City area, officials announced Friday.

Local, state and federal authorities arrested 19 people Thursday morning in a county-wide drug bust, netting a large amount of drugs, guns, cars and tens of thousands in cash, Atlantic County Prosecutor Jim McClain said in a release.

Police have accused Diaab Siddiq, a 37-year-old also known as Marshall Davis, and Ameer Stephens, 36, of running the operation, which allegedly sold "large quantities" of drugs, including heroin, cocaine and fentanyl.

In addition to the alleged leaders, authorities also arrested 17 men and women in connection with the ring, according to the release. Police are still looking for 22 others, according to McClain.

The year-long investigation netted eight ounces of fentanyl, 1.25 kilos of cocaine, 12 ounces of unpackaged heroin and more than 20,000 bags of heroin. Police value the drugs at close to $500,000, according to McClain.

Authorities also seized more than $155,000 in cash, 11 cars, 6 handguns and ammunition, the release said.

Siddiq, of Atlantic City, and Stephens, of Galloway Township, both face first-degree drug distribution charges, including organizing, supervising or managing a narcotics distribution network.

Lamarc Cochran, 30, of Hammonton, and Arshan McGee, 27, of Atlantic City, were arrested and charged with distribution of over half an ounce of heroin and conspiracy to commit distribution of a controlled dangerous substance, according to the release.
