A woman was taken into custody Thursday following a standoff outside Pasadena City Hall.
Images from the scene showed officers, including one in an armored vehicle, with their guns drawn and a woman dressed in dark clothing on a sidewalk.
Pasadena police spokesman William Boyer said the woman may have told officers she intended to harm herself.
Garfield Avenue was closed to traffic and pedestrians during the standoff.
It's unclear if the standoff had anything to do with a protest and vigil scheduled Thursday for a grandfather who was detained by immigration officers.
