Linkin Park's Mike Shinoda ... My Stalker is One Step Closer

Linkin Park founder, Mike Shinoda, is scared an obsessed fan is out to get him ... and cops are enlisting the help of Twitter to track the woman down.

According to an LAPD search warrant, cops want Twitter to fork over all info connected to user @570YtdMoFPJayTp. Shinoda thinks the recon will lead police to Tabitha Boccarossa.

Cops say Boccarossa has a love obsession with Shinoda ... she believes she's the rock star's wife.

Boccarossa was arrested in 2013 for stalking Shinoda and his wife ... she then violated a protective order in the next year by sending him letters from prison.

According to the search warrant ... Shinoda began getting weird tweets in October, including, "Omg, my feet are gross and I want to cry." And there's this one ... "Have you ever not wondered what it was like to miss every emotion you have ever felt and been built from for 30 years?"
