Sector Insp Andy Wills said: “We fully understand how difficult and upsetting this continues to be for Taylor’s family, friends and the wider community.”
“The River Taw and its estuary present an extremely challenging environment to search, particularly given tidal conditions.
“Over the past week, a rigorous and methodical search of the area has been conducted.”
He said detectives continued to carry out extensive inquiries, review information, and carefully assess any new intelligence that came to light.
Wills added: “Our commitment to doing everything we can to provide clarity and to find answers for Taylor’s loved-ones will not stop.
“Further searches can and will take place if further information comes to light.”
