SAN DIEGO -- The U.S. State Department said Thursday that it is looking into reports another American has been detained in Iran.

State Department spokesman John Kirby would not comment further on the detention of Robin Shahini.

The girlfriend of the San Diego man said Shahini's sister told her Iranian authorities took him into custody July 11 while he was visiting family in his native Iran and he has not been heard from since.

The girlfriend asked not to be identified because she has family in Iran and fears for their safety. She said she worries Shahini was detained because of his online comments criticizing Iran's human rights record.

At a news conference Thursday, Secretary of State John Kerry declined to comment on the detention.

The Revolutionary Guard, a paramilitary force charged with protecting the Islamic Republic, increasingly has targeted those with Western ties since the nuclear deal in which Iran agreed to limit its uranium enrichment in exchange for the lifting of sanctions. Officials at the Interests Section of the Islamic Republic of Iran in Washington, D.C., could not be reached for comment Thursday.

A prisoner swap in January between Iran and the U.S. freed Washington Post correspondent Jason Rezaian and three other Iranian-Americans.

Shahini, 46, graduated in May from San Diego State University with a degree in International Security and Conflict Resolution. He had been accepted to SDSU's graduate program in Homeland Security, but he has not registered for classes yet, according to university officials.

His girlfriend said he left for Iran on May 25 to see his mother, who was diagnosed with Alzheimer's. The girlfriend said she communicated with Shahini on July 10 and was expecting to hear back the next day to help him get his paperwork to the university. She grew concerned after not hearing from him.

She eventually reached his family, who told her Iranian intelligence officials came to their home in Gordon, Iran, and took him away. Authorities searched the home and took his personal belongings, she said. The family has not talked or seen him since. He had a plane ticket to return to San Diego on July 25 and had planned to start classes on Aug. 22, the girlfriend said.

"He's majoring in international security, so his passion involves peace and justice, human rights," the girlfriend said. "He's open about being a human rights advocate. But it's not only limited to Iran, he's also posted about other countries too."

She insisted to CBS San Diego affiliate KFMB-TV that Shahini hasn't done "anything wrong."

But terrorism expert Robert Baer, a former CIA case officer, told the station he's not surprised about the apparent detention.

"They don't need evidence to arrest American-Iranians," Baer said. "They simply suspect them of being American spies or dissidents. And if there's the slightest negative piece of information about them, they'll arrest them."

Baer said he doesn't expect U.S. officials to have much luck with Iranian authorities.

"They're a hard-headed bunch, Iranian intelligence, and vicious, to say the least. I don't have any hope that this is going to be settled anytime soon," he said.

Shahini left Iran in 1998 and has lived in San Diego for 16 years.

His close friend, Denera Radoonanan in New York, said he was not politically active in Iran. "I really don't' know what could have caused this," she said.

On the day Shahini's family says he was detained, July 11, Iran announced the indictments of a Lebanese man and three dual nationals. The four were arrested in connection with separate cases over the past year. Family members and representatives of the four say they did nothing wrong. All four have ties to Britain, Canada and the United States. The charges they face remain unclear.

Iran's official judiciary news agency Mizan quoted Tehran's prosecutor, Abbas Jafari Dowlatabadi, as also saying another seven people faced charges related to the unrest that surrounded the country's disputed 2009 presidential election.

It's not known if Shahini is among the seven.
