DETROIT (AP) — Authorities say a father has been charged in connection with leaving his infant and toddler sons locked in a car in a Detroit casino parking structure while he gambled inside.

Twenty-five-year-old Montez Sistrunk of Ypsilanti was arraigned Tuesday afternoon on two counts of second-degree child abuse. He was issued a $75,000 bond and his next hearing set for Sept. 13.

Detroit police say officers were called to the MotorCity Casino parking garage Monday morning after the 5-month-old and 2-year-old boys were found by an employee and rescued by a security guard. Prosecutors say the children, who weren’t hurt, had been left for about an hour.

It wasn’t immediately clear if Sistrunk has an attorney.

The Detroit News reports the children are now with their mother. Child Protective Services is investigating.
