Swedish police raid Justin Bieber’s tour bus for pot

Poor Justin Bieber is having a rough time lately.

He's getting slammed by animal rights activists for leaving his monkey at a German airport.

He took a lot of heat over his insensitive comments at the Anne Frank house in Amsterdam, a load of questionable Tweets and Instagram uploads, and now his tour bus in Stockholm was raided for pot.

Authorities in Sweden entered Bieber's tour bus after detecting a "strong smell" of marijuana, a police spokesperson told Sweden's Aftonbladet newspaper.

Police then reportedly found a small amount of marijuana and a stun gun, which requires a permit.

The Stockholm police department told TMZ that when the bus left the Grand Hotel and headed toward the Globe Arena, a officer contacted a special narcotics unit, which issued a warrant to search Bieber's bus.

The police told TMZ that the bus was not impounded and no arrests were made because authorities were not sure who the drugs belonged to. They were left on the floor of the bus and they don't know who brought it on.

The 19-year-old pop star, who is sporting some large new tattoos, told Us Weekly in a recent interview that he is "young" and "makes mistakes", but his actions are merely just a "part of growing up."
