Jesus Campos was not arrested, and neither was "Jesus Compos" as he is mistakenly refered to in a fake article titled "Police Arrest Mandalay Security Guard Jesus Compos As Second Shooter In Las Vegas Massacre" which was posted by a site named cnn-internationaledition.com and which opened:

(CNN) Breaking News - Mandalay Bay security guard Jesus Compos has been arrested accused of being an accomplice and second shooter in the Las Vegas massacre that claimed the lives of 59 people and injured more than 500.

Jesus Campos had originally been praised for his apparent heroics on October 1st, as he supposedly rushed to Paddock's suite, was shot in the upper thigh through the door, and continued to help get people to safety despite his wounds. However, FBI officials involved in the investigation now believe he was an accomplice of Paddock's, and was involved in the initial shooting as a second gunman from the other broken window in Paddock's 32nd-floor room.

The website cnn-international.com was only registered two days ago according to WHOIS records and has nothing to do with the real cnn.com:

Meanwhile the real CNN has reported that Campos was actually shot in the leg by the Mandalay Bay shooter and called in a warning to hotel security. No report has been made about his supposed arrest by any official source or mainstream news source.

The fake CNN site is part of a network of sites designed to look like local news outlets but which actually create and spread fake news, including:

• jacksontelegraph.com
• sundayinquirer.com
• sundaypost.org
• vancouverinquirer.com

Earlier the network also ran www.cnn-globalnews.com (now defunct) which was used to peddle a Clint Eastwood death hoax. Typically these sites try to keep the fake stories off their front pages in order to mislead casual visitors. Usually they are filled with regular news stories copied from other websites. Don't fall for this hoax and warn people you see spreading it on Facebook or other social media.
