At least four people, including a two-year-old child, were stabbed this morning near Manhattan's Riverside Park. A witness told NBC 4 New York she saw a woman holding a shirt to her throat, which had been cut, and asking authorities about a child who was also injured.

All are likely to survive. Police have detained a suspect, the Daily News reports:

“He was walking through the park and just started going after people,” a police source told the Daily News. The knife was recovered at the scene.

Cops said a Good Samaritan at the bloody scene helped cops take the deranged suspect into custody. The attacks occurred between W. 61st and W. 64th Sts. on Riverside Blvd.
