MOSCOW, April 29 (RAPSI) – A brother of San-Bernardino terrorist, Syed Raheel Farook, his Russian wife Tatyana Farook as well as her sister Maria Chernykh have been arrested in the U.S. and pleaded not guilty to violation of visa regime charges, Reuters reported on Friday.

All three are to be released on bond, Reuters reported.

Earlier the United States Attorney's Office for Central District of California reported that Farook, his wife and her sister are charged with sham marriage conspiracy. Allegedly Chernykh fictitiously married Enrique Marquez, a friend of the San-Bernardino terrorist Syed Rizwan Farook in order to get the U.S. immigration documents.

Marquez himself fell under investigation for alleged fraud against the U.S. immigration authorities in December 2015, Reuters reported.

According to Reuters, Syed Raheel and Tatyana Farooks are accused of making a false statement to immigration officials while under oath. Chernykh is accused of fraud and making material false statements to the U.S. authorities.

The Farooks face 5 years in prison each, while Chernykh faces a 25 year sentence based on the charges against her, as well as potential deportation to Russia, Reuters reported.

On December 2, 2015 Syed Rizwan Farook, along with his wife Tashfeen Malik, launched a terrorist attack in San-Bernardino, California. 14 people were killed, 22 were injured.
