Las Vegas gunman Stephen Paddock's brother arrested for child porn in Valley Village

VALLEY VILLAGE, LOS ANGELES (KABC) -- Las Vegas gunman Stephen Paddock's brother has been arrested in Valley Village on suspicion of possessing child pornography, the Los Angeles Police Department said.

Bruce Paddock was taken into custody at an assisted-living facility in the 5300 block of Laurel Canyon Boulevard Wednesday morning. The arrest was made by LAPD detectives, Homeland Security Investigations officials and FBI agents.

According to an LAPD statement, the investigation of Bruce Paddock was launched after evidence was found at a business in the 9000 block of San Fernando Road in Sun Valley in 2014.

"Paddock had been squatting inside the business and after his eviction, the evidence was discovered," the news release said, describing the suspect as a transient.

The evidence investigators referred to was a laptop containing hundreds of images of child pornography. Paddock had been on the LAPD's radar for years leading up to Wednesday's arrest.

The Los Angeles County District Attorney's Office charged Paddock with one count of possession of over 600 images of child pornography and 19 counts of sexual exploitation of a child.

He was booked at the LAPD's Metropolitan Detention Center and his bail was set at $60,000.

The incident appeared to be unrelated to the Las Vegas investigation, according to ABC News.

A law enforcement official told the Associated Press that the child porn case predates the Vegas shooting, and Bruce Paddock is not considered a suspect in the massacre.

The LAPD is the leading agency in this case.

Fifty-eight people were killed and hundreds more were wounded Oct. 1 at the Route 91 Harvest Festival on the Las Vegas Strip. Stephen Paddock opened fire from the 32nd floor of the Mandalay Bay casino-hotel tower.

Another brother, Eric Paddock, spoke to media following the shooting but Bruce Paddock did not.
