Police: Philly man critically injured infant son

PHILADELPHIA (AP) — A Philadelphia man has been jailed on aggravated assault and other charges after police say injuries that have left his 2-month-old son critically injured and on life support were consistent with abuse.

Twenty-year-old Brian Armstrong was arraigned Sunday on charges that also include endangering the welfare of children, simple assault and reckless endangerment.

Police were told by staff at Einstein Hospital that the boy had been injured Friday afternoon. The boy has since been transferred to St. Christopher's Hospital for Children.

Police say they charged Armstrong because his account of how the boy was injured wasn't consistent with the injuries sustained by the baby.

A Philadelphia municipal judge set bail at $5 million and scheduled a preliminary hearing for Aug. 20.
