U.K. financial regulator Financial Conduct Authority is probing 30 companies and individuals over actions that potentially endangered pensions, the Financial Times reported.

Responding to questions from a Labour party member of Parliament, Economic Secretary to the Treasury John Glen said in a letter that enforcement actions had been taken against 15 businesses and individuals for pensions-related misconduct, including scams and improper pension transfers.

The names of those being probed were not revealed.
