Justin Bieber's terrible, horrible, no good, very bad month continued earlier today, when the Los Angeles Police Department received a call this morning from Bieber's neighbor, accusing the pop superstar of battery.

"There have been allegations made–and they’re only allegations–that there was an alleged battery and some threats against an individual by Mr. Bieber," LAPD spokesman Steve Whitmore told Fuse. "We’re investigating this."

No arrests have been made so far as the investigation is still in its early stages.

"Malibu/Lost Hills Station is going to do their due diligence and when they’re done with their investigation, they'll prepare a report," Whitmore says. "It all depends on what the next step is. It could go to the District Attorney’s office; it could be unfounded. All it is is an accusation."

The accusation is the latest in what will likely go down as the worst month in the singer's career. An ex-girlfriend who talks smack on Letterman. An Instagram rant that somehow makes Lindsay Lohan look like the victim. Canceled concerts. Hospitalizations. A run-in with London paparazzi. And of course: the worst birthday ever.

April 1 can't come fast enough.
