Airbnb bans 'party houses' after shooting

ORINDA, California - Airbnb says it will take action to prevent unauthorized parties in the wake of a deadly shooting at a Halloween party held at an Airbnb rental home in northern California.

"What happened on Thursday night in Orinda, California was horrible. I feel for the families and neighbors impacted by this tragedy," Airbnb CEO Brian Chesky said.

In a series of tweets, Chesky also said on Saturday the San Francisco-based company is expanding manual screening of "high risk "reservations and will remove guests who fail to comply with policies banning parties at Airbnb rentals.
