It happened around 9 a.m. on Thursday, November 24 at the Warwick Hotel at 220 South 17th Street. Police released surveillance video on Wednesday.
Police say the 27-year-old male victim received a call from a man named Terry.
Terry told the victim he was outside the hotel and to let him inside.
When the victim met Terry, who was accompanied by two additional unknown males, he brought them up to his room.
A short time later, police say the three males pulled handguns ordering the victim inside the bathroom where they tied him up. They demanded money and the code to the safe in his room.

When he woke, the victim noticed his cell phone, $375, and a gold chain were missing.
