The Nova Scotia Health Authority is requesting the public's assistance to find Colton White, 23, who is missing from a Dartmouth hospital.

White has shoulder-length brown, straight shaggy hair and was last seen wearing blue jeans, a white and blue checkered shirt and brown leather shoes.

He is approximately six feet tall and and weighs 154 pounds.

White also went missing last month.

The man's risk increases the longer he is away from treatment, the authority said.

Staff are working with Halifax Regional Police and the Mobile Crisis Unit to locate White.
