Shannen Doherty had NO IDEA how to explain to a 911 dispatcher why she was calling from across the country to report a suicide threat -- after a NJ fan threatened to kill herself on Twitter last month -- so she settled on the "I'm an actress" routine ... and TMZ has the audio.
TMZ broke the story ... Shannen phoned police in Westhampton Township after receiving several disturbing messages from the fan on Twitter.
In the call, Doherty says, "This is going to sound incredibly strange ... my name is Shannen Doherty and I'm an actress. I'm on Twitter, sadly, and there is a girl that is threatening to shoot herself and she lives somewhere over there."
As we reported, officers were dispatched to the fan's home following Shannen's call -- and were able to confirm the fan was okay. According to the WTPD, officers met with the fan (a 27-year-old woman) who said she had no intentions of actually harming herself.
As for the rest of the 911 call, it's pretty standard -- except for the very end, when the dispatcher breaks character to tell Shannen how his co-workers are obsessed with her.
