Is this a male Sparrowhawk?

Saw this bird kill a pigeon on the CCTV camera in my back garden yesterday. Luckily it returned to the scene of the crime this morning and I managed to get off a couple of snaps with the iPhone. Can anyone please confirm if it’s a male Sparrowhawk?

It was barely as big as the pigeon it caught. Reading up online it said only the larger females can take something pigeon-sized, and that males stick to smaller birds (like sparrows I guess).
