Police: Choppers in Harrisburg are "proactive" police work
According to police, the public will notice helicopters out in Harrisburg and surrounding areas again on Thursday night.
Police say that they are looking for criminals, but not necessarily any in particular, so they are referring to it as "proactive" police work.
Officials have assured CBS 21 this is a routine procedure that has also been done previously.
Police have not said exactly when to expect to see the helicopters again, and that they may switch it up to "keep the criminals guessing."
