I saw a craft shaped like a bumerang with bright lights all over the sides of it

I was coming back from the corner shop at the bottom of our street (Tabley Road) when I saw in front of me, above the roofs of the houses in the part of our road which curves to the left, what looked like a craft shaped like a boomerang with bright white lights all around the sides. It was stationary above the roofs.
I ran into my 1st floor flat to get my phone to take pictures. When I got back out it was gone (and in my head I was willing it to come back) but about a minute later came back and was stationary again above the roofs.
I took one stationery picture and then a video. When I started to take the video the craft started moving to the right and then dissappeared above the roofs on the right.
It looked to me from where I stood about 10 metre long.
I couldn't see anything apart from the shape of it and the bright lights.
I enlarged the stationery picture and some of the video images using my phone and I will include some of the enlarged one.
