An officer responded to the station upon a request by Federal VIPR Marshalls after they examined a suspicious package that had been turned in to the station agent on 4/15/16, as lost property. Today, that same station agent flagged down a VIPR Marshall at the station and requested he take a look at the contents of the bag. Upon examination of the contents, the VIPR Marshall felt the contents were suspicious, as it contained a circuit board, a power supply box, a control switch, and miscellaneous wires. The Marshall notified SFPD who responded with their explosives detection dog. The dog cleared the package. Additionally, the Marshalls notified their Explosives Officer who examined the contents and deemed them safe. The BART officer was able to locate a name and contact information for the owner. The officer contacted the owner and determined that the bag had in fact been reported as lost on 4/15/16. The owner, a mechanical engineer lecturer at a local University, advised that the contents were props used for lectures on feedback control. There was no disruption of service. As a matter of information sharing, TSOC and NCRIC were notified. TSOC report #TSA 04-10677-16. NCRIC Tracking #20160308.
