SAN FRANCISCO (CBS SF) — An off-duty Sacramento County sheriff’s deputy who was attending a San Francisco Giants game at AT&T Park as part of the team’s law enforcement appreciation night on Tuesday helped detain a man suspected of stabbing another man near the ballpark, a San Francisco police spokeswoman said.

At about 9 p.m. Tuesday, a fight broke out between two men near the intersection of Terry A. Francois Boulevard and Third Street in the Mission Bay neighborhood, just south of McCovey Cove and China Basin Park, according to police spokeswoman Officer Grace Gatpandan, who also was in attendance at the game.
