A roundup of 30 suspected drug dealers in Charleston had netted 15 arrests by sundown Thursday, and police were continuing to serve warrants into the night.

One suspect turned himself in while Charleston Police Chief Greg Mullen and 9th Circuit Solicitor Scarlet Wilson were holding a 5 p.m. press conference at police headquarters to announce the bust.

The sweep was a result of an eight-month undercover investigation into heroin and crack cocaine distribution in Charleston's East Side and West Side neighborhoods, Mullen said.

More than 60 law enforcement officers from the Charleston and North Charleston police departments, the Charleston County Sheriff's Office, the State Law Enforcement Division and the U.S. Marshals Service fanned out throughout the city.

A SWAT team and Ninja-masked narcotics officers swarmed over a number of houses Thursday, including an apartment at 53-C Amherst St. where a dog bit a police officer, Mullen said. The dog was shot and killed by police.

Three people who were not targets of the sweep were arrested at the apartment after police found cocaine and Ecstasy.

At a house on Columbus Street, a woman who was not arrested was carried out on a stretcher to be examined by EMS. "She was upset by the raid and we wanted to make sure she was OK," Mullen said.

Small amounts of crack and heroin were seized during the raids, and three handguns were confiscated, Mullen said. "We weren't after quantities of drugs today," Mullen said. Police had warrants for all the suspects, based on undercover drug buys.

Mullen said the raids put a major dent in the city's drug trafficking network. "Anytime you can disrupt the network, you have a positive impact on the community," he said. "We're seeing people call us and tell us about people who are selling drugs. We've never had that before."

Mullen said much of the investigation's success was a result of the Solicitor's Office having assigned a prosecutor to work full time with the city's narcotics officers. "I thank Chief Mullen, along with the mayor and city council for funding this position," Wilson said.

The city kicks in $50,000 a year to help defray the cost of the dedicated prosecutor. That money comes from assets seized in drug cases, the chief said.

Wilson said her experience as a federal prosecutor taught her the value of having prosecutors work on a daily basis with front-line investigators.

Mullen and Wilson emphasized that most of the people arrested in this investigation have been on the wrong side of the law many times before.

"It is no surprise to us that many of them are repeat offenders," Mullen said. Some were out of jail on bail for charges ranging from murder to assault. Half are on probation or parole, he said.

"When you look at the names of the people arrested, you will have seen them before," Wilson said.

One suspect, George Avery Bellinger, was out on $100,000 bail, awaiting trial on a murder charge. Bellinger is accused of shooting 15-year-old Montrell Harrell at the corner of Romney Street and Athens Court in January 2007.

"The violence and the drugs go hand-in-hand," Wilson said.
