A former Secret Service agent who has once pleaded guilty to stealing from the now-defunct Silk Road website—in which he was part of the investigating team—has been arrested a day before he was scheduled to begin his prison sentence.

Shaun Bridges was arrested last week at his home in Maryland, The Guardian reported. According to the report, which quoted court documents, arresting officers discovered bags “containing Bridges’s passport and a notarized copy of his passport” and Secret Service-issued bulletproof vests that authorities believed had been stolen from the government.

Authorities also found corporate records for three offshore accounts in Nevis, Belize and Mauritius, the news outlet reported.

Bridges was due to start his prison sentence on the day after his arrest, according to reports. Last year, the former federal agent pleaded guilty to money laundering and obstruction of justice, diverting more than $820,000 worth of bitcoin to his personal account during the course of the investigation of online black market Silk Road.
