Detective Inspector Andy
Cunliffe said: "We have had a really positive response to previous appeals from
members of the public, but I really need to trace the four people in these
"I want to stress
that we are treating them as potential witnesses only but we need to speak to
them to establish what, if anything, they saw.
"This was a terrible incident and we need to understand the full
facts of what happened so I would urge anyone who recognises themselves in the
images or those who can help us identify them to call us.”
