An arrest has been made in the investigation of the theft of a high-end Gucci bag belonging to DHS Secretary Kristi Noem, a law enforcement source familiar with the investigation tells CNN. One person is in custody and multiple additional arrests are expected in a theft ring recently targeting Washington, DC’s, Penn Quarter area, the source said.

Homeland Security Secretary Kristi Noem does not believe she was targeted when her purse was stolen at a Washington restaurant, she told CBS News in an interview.

Noem was dining in Washington, D.C. when her purse went missing. Authorities believe at least two people worked together on a string of purse robberies in the city.
