A 12th Russian spy suspect has been detained in the US, the Wall Street Journal reported on Tuesday.
The 23-year-old suspect has been monitored since entering the US in October 2009 according to the report. However, the paper could not discover the identity of the unnamed suspect.
One day before the FBI rounded the 10 suspects arrested in the spy scandal, the man's visa was reportedly cancelled by US officials.
The suspected spy is currently in federal custody and is in the process of being deported.
