They will not be allowed to remain at the hotel," the police said in a statement. (Its rarely safe to film when in these crowds.) At one point, an agitator appeared to try and grab an officers weapon. Officers eventually escorted the staff out of the building later in the night and went floor by floor clearing out the hotel. Guests in 40 rooms sheltered in place during the incident, police said.
The hotel had to be evacuated.
