COHOES, N.Y. -- Cohoes officials say an onset of small fires in the downtown neighborhood areas has been determined to be suspicious in nature. They say the majority of these fires happened in the late evening and early morning hours.

No one has been harmed during these fires, but they say there is a strong concern that these incidents are not isolated.

Police say they are working undercover to determine a cause and are asking anyone who sees something suspicious to call 911.
