A shooting has been reported at the Federal Courthouse in Salt Lake City, Utah officials say.

According to the Associated Press, the United States Attorney's office says a shooting inside of the courthouse has left at least one person injured. 

The Associated Press adds that Salt Lake City police were called to the U.S. District Court building around 9:45 a.m., and USA Today adds that the U.S. attorney's office believes the shooting is connected to the trial of an alleged Tonga Crip Siale Angilau. The courthouse, which just opened a week ago boasting upgraded security, has been placed on lockdown.

The Salt Lake City Tribune reports that Angilau was shot by a U.S. Marshal after charging at a witness armed with "a pen or pencil." Mark Dressen, the FBI assistant special agent in charge, said the 25-year-old was shot multiple times in the chest, but was breathing when he was removed from the courthouse on a stretcher. 

His current condition is unknown.

UPDATE: Siale Angilau died from his injuries at a local hospital this afternoon. The Salt Lake City Tribune says he was on trial for racketeering charges, and USA Today notes that the witness he allegedly charged, 31-year-old Utah State Prison inmate Vaiola Mataele Tenifa, was testifying about how the Tongan Crips operated.

Judge Tena Campbell decided to declare a mistrial. "The court has met with the jury and and observed that most of the jury members are visibly shaken and upset by this episode,'' she wrote in a statement. "The court finds that this occurrence in the courtroom would so prejudice Mr. Angilau as to deprive him of a fair trial."
