Police are still looking for the 4th suspect involved in a brawl at two fast food restaurants after a high school football game in northwest Las Vegas.
But it has also raised questions about which law enforcement agency should handle the investigation -- Las Vegas Metropolitan Police Department or Clark County School District Police.
13 Action News Crime and Safety Expert retired LVMPD Lt. Randy Sutton helps explain the jurisdiction.
The severity of any injuries is a factor in which police agency takes the case.
"Chances are, Metro would still be the investigating agency if there were serious injuries and they would face the criminal charges from Metro, probably," Sutton said.
The other factor -- location.
"For a school fight, just a fight and it was on school property, school police would handle it," he said.
But CCSD Police also have some flexibility.
"Metro has concurrent jurisdiction so depending on the severity of the criminal activity would determine if the school police would turn it over to Metro or not," Sutton said.
In addition, if a fight starts on school property and spills over to the street, those involved could be facing charges from both Las Vegas police and CCSD police.
Sutton says school-related fights like the one a couple of weeks ago after the Centennial-Arbor View football game are not taken lightly by police and if someone is seriously hurt, the person who threw the punch could face attempted murder charges. And he says every punch and kick has the potential of causing brain injury or someone being paralyzed or even killed.
