Los Angeles Lakers superstar LeBron James has just been issued a challenge from the LA County Sheriff's department after a recent shooting of deputies.

On Saturday, two officers of the Los Angeles County Sheriff's Department (LASD) Transit Services Bureau were shot at the Compton PAX station, a local radio outlet.

A man reportedly hopped off a bus, shot the officers in the head, then fled. The LASD officers were hospitalized after the shooting.

“Moments ago, 2 of our Sheriff Deputies were shot in Compton and were transported to a local hospital,” the LASD announced in a statement. “They are both still fighting for their lives, so please keep them in your thoughts and prayers. We will update this thread with information as it becomes available.”

FOX LA's Bill Melugin tracked what he described as an “ambush” over the weekend, including posting a video of the shooting. The LASD corroborated Melugin's classification of the incident.

The shooting sparked protests in the area, including a wave of people who blocked the entrance of the emergency room where the victims were being treated.

L.A. County has posted a $100,000 reward for the arrest of the shooter, and private citizens have put up $75,000. During an appearance on KABC Radio Monday, LA County Sheriff Alex Villanueva then challenged the Lakers forward to match the total of $175,000 to help the search for the shooter.

LeBron James has been an outspoken advocate against racial injustice and police brutality, among other social issues such as voter suppression. The Lakers superstar has not public responded to Villanueva's challenge, but it will certainly not take long for LBJ to respond.

LeBron, the Lakers and the whole NBA have been active in the bubble in fighting social injustices, with players using their platform and media coverage to speak out on issues that matter to them.
