Police arrested a Marin County man Saturday evening in Mountain View after he allegedly attacked and seriously injured another man.
At 6:30 p.m. officers responded to the Mountain View Center for Performing Arts at 500 Castro St. for a report of a fight in the courtyard.
At the scene, officers saw a man, identified as 43-year-old Marin County resident Jan Neal, attacking a 55-year-old man. Officers ordered Neal to stop, but he did not respond to them, police said.
That's when an officer used a Taser to stop Neal, but the Taser was not effective and Neal continued his attack, police said.
Officers were eventually able to restrain Neal and provide aid to the victim, who suffered severe stab wounds. The victim was taken to a hospital where he is in serious, but stable condition, police said.
Neal was also taken to a hospital for treatment. He was later arrested on suspicion of attempted homicide and booked into the Santa Clara County Jail, police said.
Police said they do not yet know what caused the altercation between the two men or if they knew each other. The case remains under investigation and anyone with information is asked to call police Detective Dan Garcia at (650) 903-6624.
