(CNN) -- Justin Bieber is in Toronto to face an assault charge in connection with an encounter with a limousine driver a month ago, a source close to the singer told CNN Wednesday.
Bieber traveled to Toronto to be booked on the charge, which will happen at a police station later Wednesday, the source said.
This is the 19-year-old pop star's second arrest in a week.
Bieber was briefly jailed in Miami last Thursday after he was stopped by a police officer who said he was drag racing in a residential street. He was booked on charges of drunken driving, resisting arrest and driving with an expired license.
Sheriff's detectives in Los Angeles presented evidence this week to the district attorney in their probe of Bieber's alleged egg attack on a neighbor's house three weeks ago. The prosecutor is expected to decide as early as next week whether Bieber will be charged with felony vandalism for the incident.
"Bieber's arrest is expected within a few hours at Toronto police station," a law enforcement source with direct knowledge of the case told CNN.
Police are not publicly confirming details of the case against Bieber.
CNN was first alerted to the story through a Twitter posting from Toronto.
