"We have consulted Thomas’ family throughout the investigation, explaining the rationale behind all of our decisions."
They remain supported by specialist officers.
I’d like to reiterate that the investigation remains ongoing and ask members of the public to remain observant when out and about and report anything that may be helpful to the enquiry."
