According to authorities, the drugs found were in plain sight of the detectives. TMZ reports it was Bieber's friend, Lil Za, who was arrested while wearing a shirt that that appears to read EGG$.

Bieber is part of an ongoing investigation for throwing eggs at his neighbor's home in Calabasas, California last Thursday. After reports began circulating this morning that Bieber was being investigated for his egging hijinks, Radio.com spoke with Steve Whitmore, a spokesperson from L.A. County Sheriff's Department, about the incident, which is currently under investigation.

"We are executing a search warrant on Justin Bieber's home this morning as part of our now felony vandalism investigation into the allegations that he egged a neighbors home," Whitmore told Radio.com. "That's all I can tell you right now."
