The former head of the union representing New York City Police Department sergeants was charged by federal prosecutors with claiming hundreds of thousands of dollars in fraudulent expenses.

Edward Mullins, who served as president of the Sergeants Benevolent Association for nearly two decades, surrendered to the Federal Bureau of Investigation on Wednesday morning. He is accused of securing more than $1 million by submitting false and inflated reports seeking reimbursement for personal expenses, including meals at high-end restaurants, while claiming they were for legitimate union business.
