Justin Bieber's still partying, less than two days after he surrendered to Toronto police to face an assault charge in connection with a December attack on a limo driver.

In tweets from a downtown Toronto nightclub overnight, several club-goers described spotting the 19-year-old pop star partying until the early hours.

Bieber surrendered to Toronto police Wednesday evening, and is scheduled to appear in a Toronto court on March 10.

But early Friday, club-goers reported seeing Bieber back out on the town with friends. In fact, rumours of Bieber's appearance at Switch Nightclub, near Church Street and King Street East, circulated online before he and his entourage even showed up.

Bieber's attendance attracted attention from other club-goers, some of whom urged friends to drop their plans and head over to the downtown club.

Since Bieber's arrival in Toronto, 'Beliebers' have been hoping to catch a glimpse of the teen star. On Thursday, a video of Bieber greeting his fans outside The Hazelton Hotel in Yorkville was posted on YouTube.

In the video, Bieber, who is wearing a backwards baseball cap, is greeted by a throng of fans as he leaves in a black vehicle.

Last week, Bieber was arrested in Miami and charged with driving under the influence, resisting police without violence, and driving with an expired licence.

Bieber has pleaded not guilty to the Miami charges. A Miami-Dade County judge has set his arraignment date for Feb. 14.
