(CBS)— A 10-year-old boy and his mother were both injured after being attacked by a pit bull in the South Side Roseland neighborhood Tuesday afternoon.

CBS 2’s Dana Kozlov reports the owner had the dog on a leash when officers arrived to take the pit bull away, six hours after it escaped its owner’s home, ran down 113th street and attacked 10-year-old Devon Williams on his own front porch.

“I just laid on the ground, yelling for help,” Devon said.”

Help came, a few moments later, when Devon’s mother Lasheta Amos opened the door. But at that point, her other children say the pit bull turned on her.

Devon was bitten in the back, with a wound deep enough to require stitches. His mom’s arm was ripped apart and required surgery.

“I don’t want to see nobody get hurt like that again,” said the uncle of the dog’s owner.

He fully cooperated with animal control officer Eli Williams when he arrived. After calling for assistance, Williams and a half a dozen police officers, some with guns drawn, watched as the dog was put into the officer’s van.

Officer Williams says the owner didn’t receive a citation because he turned the dog over to animal care and control.

CBS 2 reached out to animal control about the fate of the dog but didn’t hear back.
