LeBron James has beefed up security at his L.A. home in a major way -- bringing a team of armed guards to patrol his house after learning he was targeted by a team of burglars.
As we previously reported ... the LAPD arrested 4 people who had hit more than 24 homes of the rich and famous, including Yasiel Puig, Rihanna, Christina Milian and others.
Cops say the bad guys had a list of 12 more celebrity targets -- including LeBron, Matt Damon and Viola Davis.
We're told LeBron is taking the situation very seriously -- he's got a wife and 3 kids at home -- and is taking every possible measure to protect his family.
Sources tell us ... Bron has at least 10 armed security personnel at the home -- including off-duty police officers. We're told the NBA's security team is also involved in the security plans.
L.A. Rams star Robert Woods -- whose home was burglarized -- is also working with the NFL security team to ensure his safety as well.
Cops say they believe there are more people involved in the burglary crews -- and they're asking the public for leads to track down the additional suspects.
