A dozen federal agents raided Loza's offices at city hall just hours after arresting him. The charges stem from alleged bribes Loza took from an unidentified person in the taxi cab industry, court papers show. In a 10-page indictment unsealed Thursday, authorities allege that Loza accepted separate $1,000 and $500 cash payments in recent months from an individual with "financial interests in the taxicab industry." That person, identified only as Individual Number 1 in the indictment, provided Loza a "stream of things of value," including "cash, the use of vehicles and trips," the indictment says. In exchange, the indictment says, Loza agreed to promote legislation and policies that helped the unnamed individual.
