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.

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.

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.
