A Columbia University student has admitted selling cocaine as part of what authorities called a major takedown of drug dealing on the Ivy League campus in New York City.
Harrison David pleaded guilty Tuesday to a drug sale charge. He's expected to get six months in jail and five years' probation at an Aug. 30 sentencing. He acknowledged selling cocaine to an undercover officer.
The engineering major faced the most serious charges among five students arrested in the case.
The rest have pleaded not guilty.
They are asking to get drug-abuse treatment under a program that could get the charges dismissed if they succeed.
