Reports: 'Unknown person' present at violent 2 a.m. incident involving Nancy Pelosi's husband

The violent assault against U.S. Speaker of the House Nancy Pelosi's husband Paul remains shrouded in controversy as media reports indicate at least one other unidentified person was present amid the early morning violence at the Pelosi house in San Francisco. 

The incident occurred early Friday morning when an assailant broke into Pelosi's home in the Pacific Heights neighborhood of San Francisco. The suspect, identified as 42-year-old David DePape, allegedly attacked Paul Pelosi with a hammer, leaving the speaker's husband in need of surgery. 

Details remain unclear regarding the motive of the attacker. Meanwhile, media reports of the incident generated further controversy with claims that a third person was present in the house at the time of the attack. 

Politico reported late Friday night that an unidentified third individual let law enforcement into the house after they responded to a 911 call made by Pelosi himself. 

"Officers arrived at the house, knocked on the front door and were let inside by an unknown person," the outlet reported. 

The Los Angeles Times, meanwhile, reported on Saturday that when police arrived at the Pelosi residence, "someone inside opened the door" for them. The Washington Post on Saturday likewise identified the person opening the door only as "someone."

Paul Pelosi is reportedly recovering after the incident after receiving treatment at a San Francisco hospital. 

Nancy Pelosi was in Washington at the time of the attack and afterward flew to California to be with her husband.
