The U.S. Coast Guard has suspended a marine engineer’s license amid allegations he took bribes from an executive.

The Coast Guard announced the suspension Monday after the inspector general determined a criminal investigation into former Marine Gen. Robert C. Stinson’s conduct, which involved taking bribes from the company that operates the Gulf of Mexico’s largest container port.

The inspector general’s report cited a $10,000 bribe to a former employee and a $3,000 check for a job at a marine engineering firm.

The investigation was launched by the inspector-general’s office after a whistleblower brought attention to Stinson and his relationship with the company, which he oversees.

Stinson was a former executive with the Navy’s Atlantic Fleet, the military branch that includes the Gulf.

The inspector general said the investigation also found he received payments for a “personal appearance.”

A Coast Guard spokeswoman did not immediately respond to a request for comment.
