A man has been arrested in connection with a scare at Albuquerque City Hall about a possible shooter and hostage situation that police now believe was a hoax.

Albuquerque police spokesman Tanner Tixier said Tuesday that 28-year-old Daniel Olguin was charged with breaking and entering and false imprisonment after a floor-by-floor search of City Hall.

Police in tactical gear surrounded City Hall on Monday and closed part of downtown Albuquerque after receiving reports of a possible shooter.

Employees had reported that a man was running up and down the halls yelling that there was a shooter in the building.

Police believe the situation was a hoax. An investigation was continuing.

Employees later were escorted away from the building by officers in tactical gear. No injuries were reported.

It was not known if Olguin had an attorney.
