Loud cycling noise followed by multiple helicopters

I was just outside and heard a strange noise from above. I looked up but could not see whatever was making the noise because of low clouds. It sounded kind of like a car alarm but a lower pitch. The noise was cycling and constant as it passed overhead and to the south. Minutes after, I heard a helicopter pass overhead, then two more off in the distance to the east and a finally fourth coming from the north. They formed up in a line abreast and began what seemed like a "sweep" in a northwest direction and turned southeast. They are probably visible in the sky as I type this. The helicopters have to be related to what I heard. The only other time I saw so many helicopters was durning coverage of OJ Simpson in the Ford Bronco speeding down the 91 fwy. They were media copters getting the scoop. Going to check the TV and see if there is a car chase or something.
