A team of federal prosecutors in Boston under the leadership of U.S. Attorney Andrew Lelling will oversee the sprawling college admissions fraud case against dozens of individuals, including a leading Big Law partner and Hollywood celebrities.

Federal authorities alleged dozens of people participated in a national conspiracy involving cheating on college-entrance exams. Prosecutors contend wealthy defendants, including business executives, actresses and sports coaches, took part in an alleged scheme to fix test scores and bribe entrance officials to boost the chances of family members gaining admission.

The co-chairman of Willkie Farr & Gallagher, Gordon Caplan, was allegedly caught on a wiretap saying: “I'm not worried about the moral issue here.” The firm on Wednesday said it has placed Caplan on leave.
