Never trust a Jeep full of bros.

According to the Sacramento Police Department, a silver Jeep Wrangler occupied by four white men in their 20s or 30s was the source of a smoke device that got chucked into a car at L and Sixth streets on Sunday night. Police logs say the device burned the car’s driver, who pursued the Jeep for a time before losing sight of the vehicle.

The pranklike attack was one of two reports that day regarding suspicious devices in the city.

The police department’s explosive ordinance detail also retrieved what appeared to be a grenade from a Dumpster on the 1600 block of Meadowview Road, which was discovered that morning by someone going through the trash. Bomb-squad officers removed the device for destruction, logs state.
