Acting Superintendent Craig Jackson says all of the agencies involved in the search are saddened that, despite their best efforts, they have not brought Thomas home:
"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."
Officers from Guernsey, Avon and Somerset, the JSAR and other diving agencies and dog units were involved in the investigation.

He was believed to be wearing a red t-shirt underneath a navy blue shirt with white buttons and navy jeans, he was also possibly wearing a grey hoodie.
