The lesson of today’s Blotter: Don’t trust armed teenagers.

A conflict between two rival teenage gangs devolved into a bloody attack on Wednesday in Sihanoukville.

Two 16-year-old mechanics ambushed their 19-year-old rival’s coffeshop with eight of their buddies, slashing the 19-year-old with a machete and wrecking the place.

The coffeshop owner had supposedly tried to attack the 16-year-old duo earlier that day.

Police only managed to arrest two of the teens from the attacking group as they fled the scene.
