10:05 AM PDT -- The bomb threat was bogus and not specifically targeting the Hernandez trial ... according to the D.A.'s office. People are re-entering the courthouse, and the trial will resume at 2 PM EDT.
Scary moment at the Aaron Hernandez murder trial -- when the courtroom was cleared after officials say someone called in a bomb threat.
The building was evacuated -- and people were told to wait across the street.
Earlier in the day, Hernandez's cousin was on the stand ... and says Hernandez's co-defendants seemed jittery on the night Odin Lloyd was murdered.
Officials are still investigating the bomb threat.
