Maria Barajas, a former police explorer and cadet, sent a letter to the city council in January claiming she and Chief Anthony Ruelas had a sexual relationship.
Barajas, 22, said it began in 2008 when Ruelas was a lieutenant. She said Ruelas started urging her to find another job in 2009.
Barajas said later, she was unfairly fired in connection with a car accident involving other cadets even though she was not driving.
Ruelas, a 49-year-old married father of three, was promoted to chief in August.
