The search continues for the owner of a pit bull who attacked a 6-year-old boy in Antioch earlier this month.
Police said the dog is dangerous and still on the loose.
The July 14 attack occurred in the Antioch Marina. Police said a woman and her grandson were walking in the area when out of nowhere the dog attacked the child.
"The grandmother fought the dog off," said Acting Lt. Tarra Nissen with the Antioch Police Department.
The dog left several wounds to the boy's groin and upper legs. The boy is expected to survive.
The pit bull and its owner, who authorities said is a transient, got away after the attack.
Police said the marina at the time was packed with more than 150 Pokemon Go players. Still, authorities have few witnesses or leads.

"It is obviously an aggressive animal," Nissen said. "It attacked a young boy unprovoked. It's a danger to the public."
Antioch-resident Ashley Roja said the attack is part of a larger issue of some dog owners being irresponsible.
"Why is a dog attacking somebody, especially at random? No provoking, nothing," Roja said.
Animal Control officers in Antioch said there was another dog attack last week, when two pit bulls attacked another dog.
