Javier Sanchez, a legislative assistant to Rep. Michele Bachmann (R-Minn.), was arrested last Thursday on theft charges.

According to the Capitol Police, thefts in the Rayburn House Office Building have been under investigation since earlier this year. A suspect was identified, and Sanchez was arrested and charged.

The 37-year-old Virginia resident has been charged with second-degree theft, a misdemeanor punishable by up to 180 days in jail and a $1,000 fine. It applies when less than $1,000 has been stolen.

NBC Washington reports that Sanchez was caught in a sting operation launched by Capitol Police involving a hidden camera and two envelopes of cash.

As of Friday, the day after his arrest, Sanchez is "no longer with the office," a spokesman for Bachmann said. He directed all other questions to the Capitol Police.

Sanchez joined Bachmann's staff in January, according to congressional salary data. He was previously working in the office of Rep. Virginia Foxx (R-N.C.).
