(Reuters) - Police in Albuquerque, New Mexico, were using a SWAT team to check into a possible hostage situation on Monday at a downtown government building, they said on Twitter.
"At this point in time, there is no evidence of an active shooter," Albuquerque police said in a message on Twitter. "Trying to confirm if there's an active hostage situation."
The police activity was centered on the City-County Building, a facility in downtown Albuquerque that houses city agencies and divisions of Bernalillo County, according to the police Twitter messages.
"It looks like one individual riled up some employees," Albuquerque police spokesman Tanner Tixier said by telephone.
One individual was detained and was being questioned, police later said in a message on Twitter.
A Special Weapons and Tactics (SWAT) police unit was searching the building, police said on Twitter.
The Albuquerque Journal posted photos on its Twitter page of several police cars parked outside the building.
