Police have arrested and charged a second teenaged girl in connection to the beating of a young woman on a downtown Toronto sidewalk that was videotaped and posted online.

A 15-year-old girl was arrested Tuesday and charged with assault causing bodily harm. Another 15-year-old girl had been arrested earlier.

Footage of the attack posted on the Internet shows a young woman being punched and kicked by two other women after the three have an argument on Yonge Street.

"It was quite disturbing that people would actually go to that level to assault someone," Const. Tony Vella told CTV Toronto. "Particularly when she's down and she's still being assaulted."

Police said that the three-minute video was brought to their attention by two web-surfers who saw the video online.

In the clip, the beating victim is heard telling her attackers that she is pregnant. At one point, her attackers refer to her as a "crack addicted" pregnant woman.

However, police confirmed Tuesday that the 35-year-old woman has been interviewed by officers and is not pregnant.

Both 15-year-old suspects are scheduled to appear in court on Wednesday at 10 a.m.

Meanwhile, the video has since been removed from the website to which it was originally uploaded.

Police said they're still seeking additional suspects.
