Unfortunately, my camera was in my bag at the time the bird was spotted, so hard to focus on settings at the same time as looking at the bird. It is definitely not a goshawk and size would not match other sparrowhawks. I already saw a besra two years ago in nearby area (<1km away). Unfortunately, could not check at home for the mesial stripe barring. Here is a full lightened picture via photoshop. Hope it helps...
Thanks a lot,
