A brother of Las Vegas mass shooter Stephen Paddock has been arrested in North Hollywood on suspicion of possessing hundreds of images of child pornography, according to authorities. Bruce Douglas Paddock, 58, was taken into custody at a nursing facility in the 5300 block of Laurel Canyon Boulevard on Wednesday morning. Television news footage showed Paddock in a wheelchair being loaded into the back of a van by Los Angeles Police Department officers. Documents filed Tuesday in Los Angeles County Superior Court outlined 20 criminal charges against Paddock, all related to possession of child pornography or the sexual exploitation of a child. The felony complaint for arrest warrant said that Paddock stands accused of having more than 600 images of child or youth pornography, including 10 or more images showing a child younger than 12. The investigation into Paddock began after evidence was found in a Sun Valley business where he had been squatting, the Los Angeles Police Department said
