The officer was able to tackle the suspect to the ground and hold him until a cover officer arrived and assisted with taking him into custody. The male had a $5,000 warrant for lewd acts in public. He was booked into the San Francisco County Jail for battery on an officer, resisting arrest and the warrant. The officer did not sustain any injuries.
