The Bel Aire police chief has called for tougher animal control regulations after a teenager was hospitalized in a bull terrier attack.

Chief Darrell Atteberry says the dog bit the 13-year-old boy last week on the arms, stomach and genitals while visiting a friend. He says police previously responded to two separate attacks by the same dog in 2012 when the family lived in Wichita.

Atteberry says the boy needed stiches and there have been unspecified medical complications because of the injuries. No charges have been filed.

He says city regulations need to change to better protect people and should coincide more closely with stricter county laws.

The dog was turned over to animal control where it was being observed for 10 days.
