The pit bull that was shot and killed by police near Golden Gate Park on Tuesday night after it bit two men was reportedly in the custody of Animal Care and Control last month. Another pit bull that was involved in the attack but was not killed also was in city custody in December.
The dogs ended up in custody after a vehicle containing them was towed last month, according to Animal Care and Control.
Department spokeswoman Deb Campbell said the owner of the dogs has been identified, but she did not know if he would be cited for Tuesday's incident. His name was not released.
The killing also marked the second officer-involved shooting of a pit bull in the past week.
In Tuesday's incident, two men were bitten by two pit bulls near Lincoln Way and 25th Avenue about 10:40 p.m., Officer Albie Esparza said. While one dog was killed, the other escaped. But it was picked up by Animal Care and Control early Wednesday morning near Haight and Stanyan streets, Esparza said.
The two male victims, one 53 and the other 43, were bitten multiple times, Esparza said. One victim was taken to the hospital and the other refused medical treatment at the scene. They are both considered to be in stable condition.
The dog found Wednesday will be housed at Animal Care and Control until a hearing before the Police Department's vicious and dangerous animals unit determines its fate.
Meanwhile, on Saturday in Potrero Hill, officers were investigating a complaint about a squatter living with a dog in a vacant unit in the 1000 block of Connecticut Street about 10:30 a.m.
The officers were apparently familiar with the suspect and his dog, named Psycho, police said. Police knocked on the door and said they could hear Psycho growling and snarling inside. The suspect, who was not in the unit, reportedly walked up to the officers and seemed angry. He told the officers he would be leaving that day.
Psycho was still behind the door of the unit, barking and scratching, when the suspect reportedly kicked the door open, releasing the dog. Psycho reportedly charged toward the officers and the suspect made no move to stop the dog, according to police.
The officers retreated and the dog focused on one officer and ran at him aggressively, police said. The officer was then backed into a wall and fell to the ground as the dog lunged at him.
He shot the dog once, killing it.
The suspect, identified as Pollard Alston, 54, of San Francisco, was arrested and booked on charges of assault on a police officer, assault with a deadly weapon and trespassing. However, his case was discharged by the District Attorney's Office due to insufficient evidence, spokesman Alex Bastian said Wednesday.
