Rio Rancho was responding to a request from Albuquerque Police Department as they have on similar occasions in the past.
The protest took place along Central Avenue and in Downtown Albuquerque, beginning around noon and gradually becoming more unruly during the evening.
Marchers were calling for police accountability in the wake of the police shooting on March 16 of the homeless mentally ill James M. Boyd.
Rio Rancho officers trained in crowd management arrived on scene in Albuquerque around 7:30 p.m. and remained on that duty until about 11:30 p.m.
The officers had personal protective equipment, nonlethal munitions and one armored personnel carrier, the release said.
Reports of the incident said police used tear gas after 9 p.m. in an attempt to disperse the crowd. Six people were arrested.
The Rio Rancho release said no Rio Rancho police were involved in the arrests and none received injuries
