Why Isn't the LAPD Investigating Charlie Sheen?

Brooke Mueller insists threats were made, yet there have been no signs of an investigation

Charlie Sheen proved he is as erratic as they come during his media meltdown tour, and he reputedly even turned violent toward ex-wife Brooke Mueller during an altercation in the Bahamas. And since this is Sheen we're talking about, this dispute wasn't your typical marital spat; it reportedly involved threats of beheading and a penknife to the eye from Charlie.

So what's stopping the LAPD from investigating?

Brooke has filed a temporary restraining order (TRO), but that's not enough to bring in law enforcement.  "We cannot act on a report in her TRO," LAPD Officer Norma Eisenman tells us. "Unless she comes in and does a report, we can't do anything."

Despite the very violent nature of the threats mentioned in the TRO, Eisenman still insists that Sheen's ex-wife will have to take further action. "She has to file a crime report," she says.

Sources close to Mueller have repeatedly told E! News that she hopes to reach some kind of a deal with Sheen and won't be getting the cops involved. A court hearing on the TRO is set for March 22.
