Louisiana Attorney General Charles C. Foti began an investigation into the state's $1.1 billion Municipal Police Employees' Retirement System, Baton Rouge, according to Kris Wartelle, spokeswoman for Mr. Foti. Mr. Foti was asked by Clinton, La., Police Chief Eddie Stewart to look into the plan's investment strategy after he learned the plan was losing money, Ms. Wartelle said. "Just because someone has made a bad investment does not necessarily mean there has been any criminal wrongdoing," she said. Mr. Foti will begin by interviewing board members and reviewing the plan's external managers, she said; the timeframe has not been determined. Plan officials could not comment by press time.
