Drug sting gone-wrong ends in mass brawl between two undercover cop teams on the streets of Detroit

The encounter started when two special operations officers from the department's 12th Precinct were working on a drug bust on Andover, a notoriously drug-heavy area of the city.  

The officers were pretending to be dealing narcotics in hopes that eager customers would approach before being arrested and having their vehicles seized. 

But problems started when another group of undercover special operations officers from the 11th Precinct approached, posing as buyers.

When they showed up and started speaking, the 11th Precinct officers ordered the other cops to the ground - not realizing they were fellow boys in blue.

But scenes quickly descended into a farce with the two teams of police fighting each-other as the stunned homeowner watched on.

Obviously they just need more money.
