Violence along the border has left visible scars in Matamoros, where streets stood half empty in the days that followed. A total of 52 vehicles were burned out during the unrest, leaving parts of the city covered in ash. Businesses closed their doors and many residents stayed away, adding to the sense of a city on pause. The financial toll is estimated at up to 30 million pesos in losses. The turmoil broke out after the detention of Axel Alfredo "N", who is known by the alias "El Titan". His arrest appears to have triggered the wave of destruction that hit the border city.
