The police station is no longer a safe place on CSI: Las Vegas.

The LVPD headquarters will be an all out mess in episode 19. Titled "The Fallen," the Louis Milito ("De Los Muertos," "Check In and Check Out") directed installment is sure to pull on a few heartstrings.

Although the series has yet to reveal a plot summery, the CSI Writers' Room has let slip that 19-year-old Brendan Meyer will be guest staring.

"We're psyched to have @BrendanKJMeyer in 1419, a special episode taking place almost entirely at LVPD," the CSI Writers' Room tweeted on Tuesday.

In addition, one man will wind up on the autopsy table while the cops roll in the riot gear and the big guns (see gallery above).

"Not a good day in the police department!" Milito tweeted during filming, adding, "PD is supposed to be safe..."

However, fans still have several episodes to go before the action-packed events of "The Fallen." The CBS drama broadcast their Valentine's Day episode, "Love For Sale," on Wednesday and will soon air "Killer Moves," "Long Road Home," and "Uninvited."

CSI: Crime Scene Investigation airs Wednesdays at 10 p.m. ET on CBS. Click the video below to see a preview for the series' most recent episode.
