Chula Vista police spokesman Bernard Gonzales said investigators had identified Romeo Montillano as a suspect in a Dec. 8 robbery at a Kmart.
Gonzales says investigators learned that Montillano had signed up for the February Police Department entrance exam.
The 40-year-old man was arrested Wednesday when he arrived to take the test.
Gonzales said that when Montillano was taken into custody he asked if he would still be able to take the exam.
Police said Montillano was arrested for investigation of robbery, making criminal threats and grand theft. He remained in jail Saturday in lieu of $110,000 bail.
