CHARLESTOWN, R.I. — A police chief is asking the Rhode Island State Police to investigate possible steroid use in his department after a former officer pleaded guilty to trafficking steroids and money laundering.

Charlestown Chief Jeffrey Allen is asking the state police to investigate his department based on information from federal authorities. Allen says an inquiry by the state police will help avoid conflicts of interest.

His request comes after the conviction of former Charlestown officer Evan Speck last month. The 34-year-old resigned after federal agents raided his home in Westerly in March.

Prosecutors say Speck received $536,000 from the sale of steroids and other drugs.

Allen says if state police find wrongdoing, “the chips will fall where they may.”
