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.
