A federal agency on Wednesday sued ITT Educational Services, a major owner of for-profit colleges and trade schools, alleging predatory lending and other charges. It is the first suit against a for-profit education company by the Consumer Financial Protection Bureau, created in 2011, the bureau said. The bureau said the company lured students with zero-interest borrowing that had to be repaid after the first year, then pressured them to take new loans with very high fees and interest, knowing that most of them would default. ITT called the claims “without merit.” The company’s ITT Technical Institutes have about 140 campuses and 55,000 students.
