A fire at a mobile home in the northwest part of Portage la Prairie last night remains under investigation.

It's now believed the blaze began underneath the home. That's from a Portage Fire Department official.

A woman was the only occupant of the mobile home when the fire broke out, but she was sleeping at the time.

Thanks to a neighbour calling, she was able to get out unscathed.

The woman's father also lives there, but he wasn't at home at the time.
