Powder found in Vegas hotel room

LAS VEGAS, NV Authorities say a substance found Tuesday in a room at the Excalibur hotel-casino is not hazardous but have not disclosed what the substance is.

The man wasn't sickened and hotel business was not interrupted after he reported returning to his room and finding the powder on his bed about 9 a.m.

The investigation comes after officials found the toxin ricin at another Las Vegas motel last week. Authorities also searched the Excalibur on Friday in connection with that case, but no ricin was found.

Hotel officials say the searches involved different rooms.
