I'm not confident I'm working with/at maximum resolution. Probably need to get back to "first principles" for the definitive enhancement. In the same breath I'd say: Safe to say "there probably is no single magic bullet enhancement-frame". One is therefore encouraged to "mentally amalgamate" salient image-info.

I would observe the hat size as large - larger than one might expect for what appears as a moderately narrow face. Also, there is a watch-like item on the perp's left cuff. I'm not convinced it's a watch for the sole reason it appears on the external surface of the sleeve. Pretty unusual and hopefully will strike a "resonant chord" with a viewer.
The camera appears to be clipping (maxing-out) on the more reflective surfaces. This might speak to elevated, ambient electronic infra-red illumination-levels (luminosity). It could be from street lighting but could also be (emanating) from camera-based LED's. I don't know - either way it's troublesome - I've highlighted these clipped regions in the hopes of providing/gaining (a) better perspective. There are security cameras that detect this "backwash" and auto-adjust (lower) the brightness of the camera LED's.
Good time to emphasis the importance of having your camera "up to speed" -- on various fronts -- including having adequate resolution along with dynamic brightness compensation (specifically as relates to IR washout) and of course having a lens that's free of water droplets and/or accumulated atmospheric grime. Time to audit your system in light of not-so-recent techno-advances and year-round Boxing Day pricing!
Getting back to the task-at-hand;
I've engaged ultra-contrast in this following footage. I was hoping to peer into the "shadow smile" -- ostensibly to locate a mouth or perhaps a moustache. I don't think I'm seeing either. There is room for some additional enhancement in this direction. There appears a weird glitch (tongue-like protrubence) close to the end. Probably just that: a glitch.
The "watch" stands out well in this footage. As does a persistent dark spot on the weird bandana. I would note the knot of the bandana (behind perp's left ear) interferes somewhat with the assessment of exactly how prominent the perp's ears are. I'm not going to hazard a guess - pretty critical observation.

Trust this all as reasonable. Stay tuned - More soon!
