Prince George, B.C.- Emergency crews  have been  scouring the Otway Road area,  trying to find the source of  a noise, that  made  windows rattle on the north side of  the Nechako River at around 8:40 this evening.

While one  area resident  tells 250News, the  noise “reverberated  for a long time”,  emergency  crews have yet to pin point the source of that  noise.

Some have described it as a very loud rumble that lasted long time while others likened it to the sound of of a blast.

It is not uncommon for CN to shunt trains along the line that runs  along Otway Road on the south side of the Nechako River,  but  area residents who are used to  the sound of shunting trains says this noise,  certainly wasn’t that.

Police, fire and ambulance all  converged on the   area,  but have yet to identify a possible source  for  what  some  area residents say sounded like an explosion.  At this point, there has been no word from emergency responders as to the possible cause .

250News will  keep  you posted.
