A man suspected of robbing a California store has landed in custody after turning up to take a police entrance examination in the same town.
Chula Vista police realised Romeo Montillano was a suspect in the December robbery when he signed up for a police test two months later.
Detectives doubted he would show up after he phoned in from Las Vegas to say he was having car problems.
But he arrived on time, by bus, only to be arrested by astonished officers.
Detectives were waiting at the registration table when he walked up and signed himself in as Romeo Ogilve Montillano, Chula Vista police spokesman Bernard Gonzales was quoted as saying by the San Diego Union-Tribune.
Momentarily stunned, they called Mr Montillano out of the exam room and into a nearby office, where they arrested him for the robbery of the town's KMart discount store on 8 December last year.
In the robbery, a man stole a TV set, a DVD player and a telephone from the store, according to reports in the Union-Tribune.
During his arrest, Mr Montillano asked if he would still be able to take the exam.
When told that he could not, he then asked if he could re-apply and maybe take the test later, Mr Gonzales added.
Romeo Montillano was arrested for investigation of robbery, making criminal threats and grand theft, and remained in jail on Saturday in lieu of $110,000 (£77,000) bail, the Associated Press reports.
