Hazmat, explosives teams at Ottawa hotel after possible threat

(Reuters) - Ottawa police said on Wednesday that hazardous materials and explosives teams were on site at a hotel that had been evacuated overnight because of a "possible threat", and also said a suspect could still be inside. "We believe that there is still a suspect inside, so it's an ongoing police operation," said Ottawa Police spokeswoman Carole Lavigne, but did not specify the nature of the threat. Several nearby roads were closed by the Chimo Hotel located in Ottawa.
