Justin Bieber's mansion was allegedly littered with all sorts of drug paraphernalia and substances new reports indicate.

Bieber's house was raided by police last week after he was accused of egging the home of a neighbor. The singer's friend, Lil Za, was arrested on cocaine possession and supposedly had a smoking room in Bieber's home, reported TMZ. 

Lil Za was taken into custody and released on $70,000 bail, reported the Daily News.

"The cocaine, I believe, was in plain view of the deputies when they were looking for the other evidence," Lt. David Thompson told reporters according to the Daily News. "(Bieber) was not connected to that cocaine other than the gentleman was staying at his residence."

Daily Mail reported the LA County Sheriff's Office found two large cookie jars filled with marijuana, three bongs, and cigars. All of these items were reportedly in plain view. 

According to Daily Mail, sources close to the singer have urged him to check into rehab or to seek help as his behavior has been getting a lot of bad press lately. 

"People around Justin want the best for him and hope that at some point he'll recognize the need for some help," said the source to mail Online. 

A Los Angeles Sheriff Dept. spokesperson told FOX411 the warrant was given at 8 a.m. PST.

Eleven L.A. County Sheriff's police vehicles allegedly arrived at Bieber's gated community searching for evidence connecting the singer to an egg-throwing case related to a neighbor.

Sources told TMZ that the 19-year-old singer was being detained in his garage as deputies performed the warrant.

According to a report by TMZ, there was $20,000 worth of damages to the neighbors home because of the egg throwing incident. The home had a special venetian plaster on it that will cost an estimated $15,000 to redo, and an additional $5,000 in various damages.

The neighbor claimed he audibly caught Bieber on camera doing the egging, and can be heard yelling, "I got another one for you actually," after the angry neighbor informed the singer he saw him.

Additionally Bieber can be heard hurling an expletive as well. The neighbor then informed his daughter to call the cops.
