Reuters reports that an Iranian-American man who was detained in Tehran last week along with three journalists was released on Wednesday.

The remaining three detainees are the freed man’s wife, who according to Reuters is an Iranian-American photographer, Jason Rezaian, the Tehran correspondent for the Washington Post, and his wife Yeganeh Salehi, a correspondent for the UAE-based daily, The National.

The four were arrested on Tuesday, and Rezaian’s home was raided by security forces, who confiscated his computer and other items.

Authorities confirmed the arrests and said the detainees are still under investigation.
