BROOKLYN - Hundreds marched across the Brooklyn Bridge and straight to City Hall today to raise awareness about teen dating violence.

It marked the third annual New York City Teen Dating Violence Awareness Walk-a-Thon. It was sponsored by the Healing Center, a domestic violence counseling center.

The marchers started off with a rally at Cadman Plaza before heading across the Bridge to make speeches at City Hall.

Experts say teen dating violence affects one in four teens nationally, and is often under-reported. Organizers are hoping to diminish that statistic, and to spur lawmakers to provide more funding for outreach centers that help teens facing dating violence.
