A Metro Transit Police officer from Washington, D.C., has been arrested and charged with attempting to provide material support to ISIS.
The officer was identified as Nicholas Young, 36, according to WJLA. Young had reportedly been with the transit police since 2003.
Young was allegedly discovered to be sending money to people he believed to be associated with ISIS. The people he was delivering money to turned out to be undercover FBI agents.
Law enforcement officials have been keeping an eye on Young since 2010. In that year, an acquaintance of Young's, Zachary Chesser, pleaded guilty to providing material support to terror groups.
An affidavit indicates that Young told FBI officials that he traveled to Libya twice in 2011 and had associated with rebels who were attempting to overthrow the government of Libyan dictator Moammar Gadhafi.
On other occasions, Young reportedly told the undercover agents "how to evade law enforcement detection by utilizing specific travel methods, and advised a FBI confidential human source to watch out for informants and not discuss his plans with others."
The indictment reveals much of the same -- that Young was focused on extremist activity abroad rather than in the immediate D.C. area, according to The Washington Post.
"Obviously, the allegations in this case are profoundly disturbing. They’re disturbing to me, and they’re disturbing to everyone who wears the uniform," said Metro General Manager Paul J. Wiedefeld in a statement.
Young was due to appear in court on Aug. 3. He faces up to 20 years in prison if he is found guilty.
