Authorities have discovered cocaine in Justin Bieber’s home.

Police raided the 19-year-old singer’s Calabasas, California estate on Tuesday following allegations he egged his neighbour’s house last week.

And according to TMZ, cops found cocaine in the residence during their search.

Justin’s friend Lil Za has apparently been arrested for drug possession. Although the Baby crooner isn’t exonerated from possible charges related to the egging incident, the outlet reports he is “not connected” to the cocaine that was uncovered during the raid.

During a press conference, police officials told Celebuzz that they are taking the egging allegations seriously.

“It is a felony crime. I get that it was done with eggs which makes you feel that it was at a lower-level crime,” an authority explained.

Justin has been accused of causing $20,000 worth of damage to the front portion of his neighbour’s house.

And authorities claim his fame has nothing to do with their investigation into the matter.

“None of this has anything to do with him being celebrity. We determined this was a felony crime that had evidence,” the police spokesperson insisted.

“We hope understanding the gravity of this will change the behaviour. We hope that we can the neighbourhood the quality of life they deserve and hopefully this will do it.”

It is believed Justin will undergo further questioning in relation to the egging incident with his attorney present sometime in the near future.
