Swarms of fans gathered outside of a Toronto police station today to catch a glimpse of pop star Justin Bieber.

The singer turned himself into local authorities in his home country after police there summoned Bieber to answer questions about an assault investigation.  Details about the case are few but it is said to revolve around Bieber, his bodyguards and a limo driver.

The alleged incident took place December 29th while Bieber was in Toronto to attend a hockey game.  The singer's interaction with Toronto police comes less than a week after his arrest in south Florida for a DUI charge related to an alleged drag racing incident.
