They quickly discovered the man had several weapons and ammunition in his hotel room.
The hotel the man was staying at was preparing a massive New Year's Eve celebration.
Investigators say security officers called police after the man became belligerent and refused to be subdued early Sunday at the bar at downtown Houston's Hyatt Regency Hotel. He was then arrested on charges of unlawfully carrying a weapon and trespassing.
Less than 24 hours before party goers were set to pack the lobby of the Hyatt Regency Downtown police made a major arrest.
"The safety and security of our guests and colleagues is our top priority, and consistent with the hotel's prepared security plans, heightened measures are in place on New Year's Eve", hotel manager Tom Netting said in a statement reported by the Houston Chronicle.
Senties says investigators don't believe the man intended "to use the weapons or to cause any kind of issue".
Police are waiting to interview the man until he has sobered up, Macintosh said. The name of the suspect is not being released at this time.
Houston Police Chief Art Acevedo tweeted earlier Sunday that the situation at the hotel had been "contained" and authorities weren't aware of any specific threats to the city.
Police are still investigating the incident.
