San Francisco officers tackled a man in the South of Market area who was cursing and jabbing a knife at passersby, police said Saturday.

The incident happened at about 10:15 Friday morning on Fourth Street near Mission Street. One officer suffered minor injuries.

“Officers arrived on scene and observed a subject waving a knife and yelling incoherently,” the San Francisco Police Department said in a statement.

There were several events taking place in the area, where foot and vehicle traffic is often heavy. Police said the man did not respond to their commands to drop the knife, so they made a plan to subdue him.

One officer tackled the man from behind, and others restrained him once he was on the ground. One officer used “knee strikes” in the process, officials said. Police recovered his knife.

The man, whose name was not released, was handcuffed and taken to a local hospital for an evaluation.

“All officers activated their body worn cameras during the incident,” the statement said. “As with any incident involving a use of force, a supervisory evaluation will be conducted to ensure that the use of force was within policy.”
