Updated (Feb. 24) — The boy underwent surgery, and will not lose his arm, as doctors originally feared. One of the two dogs involved in the attack has been found.

A Frankford boy is in critical but stable condition after being attacked by a pitbull yesterday morning.

The 10-year-old boy was bitten on his arms and legs in a field on the 1900-block of Wakeling Street Sunday morning. He was taken to St. Christopher’s Hospital for Children. Reports say the boy is in custody of his grandfather, and the dog belongs to a neighbor. It’s unclear if the dog is still in its owner’s possession.
