Strange light, was inspected by 3 helicopters.. Please read.. I need to know if others experienced something like this..

So my boyfriend and I walked outside to smoke, and we saw this strange object in the sky, moving in slow motions, back and forth, up and down... It was so bright, and it seemed as if it flashes red at some points.. So we continued to watch, and then we saw a helicopter approach it,a and it shined it's lights directly down onto it..  So my boyfriend and I were really intrigued now..  That helicopter left, and about 5 minutes later, we see this other one coming, and my boyfriend said " be ready to see something strange happen.."  And it passed it at first, then turned right back around, and shined it's lights down straight on it, and circle it.. It circled it for about 10 minutes... And I was just, in shock..  The helicopter left, and a third one came along, and did the same thing.. So we assume that people have been calling and reporting this strange object. My boyfriend and I went inside for about, 20 minutes, and went back outside, it had vanished. I ! just want to see if others had witnessed this, or something similar. I want to know what this was, and what's going on.
