NEW YORK - There's been a big meth bust spanning locations in New York City and New Jersey. 

Chopper 2 spotted boxes being carried out of buildings in Washington Heights. 

That's one site where, sources say, the Department of Homeland Security and NYPD executed 10 search warrants, starting at 6 a.m. Wednesday. 

In all, they arrested more than 12 people. 

Authorities also searched locations in Harlem, the Bronx, and in New Milford, N.J.

The U.S. Attorney-Southern District will be handling the case.
