Only the first and last names of the suspects are known, there are photos, but nothing else: no passport numbers, no visa numbers, no additional data.
CCTV pictures recovered by the British police were actually shots taken from a series called ‘KGB Spy’. So, in fact, Skripal poison suspects were British actors in a TV drama, according to a Facebook post by producer Michael Killigan.
No evidence given. Internet searches produced no trace of a home-grown drama called 'KGB Spy.' There is no record of a Facebook account for a TV producer by that name, according to The Sun.

On Sunday 4 March Sergei and Yulia Skripal were poisoned in Salisbury with a military-grade nerve agent of a type developed by Russia. As for the scar on her throat, news outlets, including the BBC and Telegraph, have described it as a result of a tracheotomy, a surgical procedure which opens a hole in a person's windpipe to help them breathe. She has not shared specifics of her treatment, but described it as "invasive, painful, and depressing." http://uk.businessinsider.com/skripal-poisoning-yulia-skripal-neck-scar-hints-at-painful-recovery-2018-5?r=US&IR=T
