The dogs, named Koji and Gustav, were returned at 6 p.m. PT to the Olympic Community Police Station near downtown Los Angeles, an LAPD spokesperson said.
The investigation is ongoing and LAPD is still working to locate possible suspects from Wednesday’s attack, a spokesperson said.
The dog walker, who was shot by the assailants, is listed in critical condition but is expected to recover, the LAPD said earlier Friday.
Home surveillance video shows attack
Among the pieces of evidence being investigated is surveillance video that shows the horrific attack.
The footage, recorded by a home surveillance camera and obtained by CNN, shows the man walking on what police identified as Sierra Bonita Avenue in Hollywood when a light-colored sedan slows and stops next to him.
At least two individuals can be seen exiting the vehicle, accosting the dog walker as a physical altercation ensues. The footage also contains vivid audio in which the victim can be heard telling the attackers, “No, no” as he struggles with the men.
One attacker restrains the victim, as the other appears to point a gun. A gunshot can be heard, and the victim falls backward as the assailants race back to the car.
“Oh my God, oh my God, help me,” the man shouts before the car drives off. As neighbors rush to the man’s aid, he continues to scream for help, saying he’s been shot in the heart and lungs and that two dogs have been stolen.
In an interview with CNN on Friday, Lady Gaga’s father said the dog walker is a close friend of his daughter. He remains hospitalized but is “recovering well,” a source close to the singer told CNN on Thursday.
“My beloved dogs Koji and Gustav were taken in Hollywood two nights ago,” Gaga wrote. “My heart is sick and I am praying my family will be whole again with an act of kindness. I will pay $500,000 for their safe return.”
“If you bought or found them unknowingly, the reward is the same,” Gaga said.
She praised the dog walker. “You risked your life to fight for our family,” she said. “You’re forever a hero.”
