Authorities say the brother of Las Vegas shooter Stephen Paddock has been arrested in Los Angeles on suspicion of possessing child pornography.

Bruce Paddock, 59, was arrested Wednesday in North Hollywood by authorities from LAPD, FBI and Homeland Security.

Paddock is facing one count of possession of child pornography and 19 counts of sexual exploitation of a child.

A felony complaint says Paddock possessed more than 600 images of child porn between Jan. 1 and Aug. 30 of 2014.

According to a news release from the Los Angeles Police Department, the investigation of Paddock was initiated after evidence was discovered inside a business where he had been squatting after his eviction. At the time, Paddock was a transient and could not be located.

Bruce Paddock is not considered a suspect in the Las Vegas shooting. The official says the child porn case predates the shooting. It wasn’t immediately known if he has an attorney.

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.
