For Thursday's breaking news, see: Disappearance of Calgary mother and toddler being treated as homicides

A mother and her toddler have gone missing in southeast Calgary, police say.

The Calgary Police Service has issued a request for help from the public to find Jasmine Lovett and her daughter, Aliyah, who is almost two years old.

Lovett, who's described as being in her mid-20s, lives in the community of Cranston with her daughter and usually stays in regular contact with her family.

However, police say she hasn't been heard from since April 16. The mother and daughter were reported missing a week later on Tuesday.

Officers have not been able to find them, so they put out the public call for help early Wednesday afternoon.
