Authorities shot and killed a pet pit bull after the dog attacked an 8-year-old girl Saturday afternoon, critically injuring the child.
The two girls, ages 8 and 15, were in their home on the unit block of Adelene Drive in Newark, Delaware around 1 p.m. when the dog began attacking the younger child, according to police.
The teenager called 911 and, while police headed to the scene, the pit bull remained in the room, preventing the children from escaping, authorities said.

The 15-year-old was able to carry the critically injured child out of the room once police arrived, according to officials.
But the dog remained aggressive, which hampered the officers ability to provide medical treatment to the hurt girl and led to an officer shooting and killing the dog, police said.
Authorities transported the girl to A.I DuPont Children's Hospital, where she was then airlifted to the Children's Hospital of Philadelphia.
She remains in critical condition at CHOP, officials said.
