Michigan — Police say a toddler accidentally shot and injured two other children at a home day care facility in suburban Detroit.

Dearborn Police Chief Ronald Haddad says a preliminary investigation has revealed the toddler "accessed a handgun and the weapon discharged" about 10:20 a.m. Wednesday.

The wounded children both are believed to be three years old. They have been hospitalised in critical, but stable condition.

Haddad says the gun was kept in the Dearborn home, west of Detroit. Several other children were at the home at the time of the shooting. Those children were taken to the police station to be reunited with their parents.

The shooting remains under investigation. No one has been charged.
