No charges will be laid against a mother after an Amber Alert was issued over the disappearance of three children from their Fort Saskatchewan, Alta., home Thursday.

An Amber Alert was issued just after noon amid concerns the children had been taken from their home without any winter clothing or necessities.

RCMP had initially alleged the children were abducted by their mother. A news release said police were notified by the woman's husband that he had awoken at about 4 a.m. to find she left the home with the three children.

But the Amber Alert was called off after the three children and mother were located in Calgary "safe and sound," police said.

The mother called police shortly after hearing the Amber Alert had been issued, Fort Saskatchewan RCMP said.

RCMP said they had received information earlier Thursday morning that led them to believe there was a concern for the health of the mother and the medical needs of at least one of the children, and that's why the alert was issued.
