The stabbing was reported in the downtown area, though specific details about the location and time were not immediately available. The victim, whose name has not been released, was pronounced dead at the scene or shortly after, according to authorities.

The 54-year-old suspect was taken into custody by Dallas police. His identity has not been made public pending formal charges. Police have not said what led to the stabbing or whether the two knew each other.

The killing adds to concerns about safety in the city's central business district, where residents, workers and visitors have increasingly called for a visible and compassionate response to violence. Community advocates have urged city leaders to pair law enforcement with mental health and social services to address the root causes of crime.

Dallas police are continuing to investigate. Anyone with information is asked to contact the department.
