A 5-year-old student was found with eight grams of a substance suspected to be crack cocaine at a Northwest Washington charter school yesterday, prompting an investigation in which the child's parents were arrested on drug charges, police said.

D.C. police said staff members of the Community Academy, in the 1300 block of Allison Street NW, called them to the school yesterday morning. When vice investigators arrived, police said, they found the student with the suspected crack.

During an investigation, police said, five grams of crack cocaine and 165 grams of marijuana were seized from the home of the child's parents. Barbara Burke, 38, and Dennis Wilson, 45, of the 800 block of Jefferson Street NW, were charged with possession with the intent to distribute cocaine and marijuana, police said.

The couple are scheduled to be arraigned in D.C. Superior Court. The 5-year-old and a 3-year-old sibling have been placed in the custody of Child Protective Services, officials said.

Commander Melvin Scott of the 4th Police District said in a statement issued by police last night that the school took "swift action." Scott could not be immediately reached last night, and school officials were not available for comment.

Community Academy was described in August by the D.C. Public Charter School Resource Center as a standards-based school founded by the Urban Family Institute, a community organization created to provide families with needed support and resources.
