Sergio Calderón, a 22-year-old resident of San Francisco's Bernal Heights neighborhood, that four men and two women came to his home, claiming to be from the San Francisco Police Department. According to Calderón, the group flashed badges of some kind and said they'd traced a missing iPhone prototype to his apartment.

That's the that CNet earlier this week. An Apple employee had reportedly lost the phone at Cava 22, a bar in San Francisco's Mission District. Although CNet reported that police had searched a man's apartment in Bernal Heights, San Francisco police that they had no knowledge of the incident, and that no police report was filed.

One possible explanation: Those visitors were pretending to be police officers.

Calderón said the group threatened to call immigration on his relatives who were also staying at the apartment, although Calderón said the relatives were all staying in the U.S. legally. Still, Calderón let the visitors search his home and his car, and gave them access to his computer. The group also reportedly offered $300 to Calderón in exchange for the iPhone prototype. Finding nothing, the group left, but one of the men left his phone number in case Calderón wanted to share any more information.
