Rescue crews respond to plane crash at N.B.

Search and rescue crews are on the scene of a small plane crash in the Cumberland Bay area of New Brunswick.

Cumberland Bay is a small community, located on the shore of Grand Lake, just east of Fredericton.

There are unconfirmed reports that the plane went down in Grand Lake, though it's unclear how many people were aboard.

There is no word yet on any survivors or casualties.

Witnesses say the plane crashed about 4:20 p.m. AT, according to Brad Perry, a first-year journalism student at the New Brunswick Community College in Woodstock, who was at the scene.

He said helicopters and boats appear to be focusing on an area known as Goats Island, located between Cox Point and Flowers Cove.

An ambulance has reportedly been asked to set up in Flowers Cove.

A Cormorant helicopter and a CC1 aircraft from 14 Wing Greenwood in Halifax are among the rescue aircraft responding.

Witnesses to the search effort say the aircraft are flying in a grid pattern over the area.

Local emergency crews are also on the scene.
