Superintendent Jen Appleford, from Avon and Somerset Police, said the community was in shock and Aria’s family were being supported by police.
“It is impossible to adequately describe how traumatic the past 36 hours have been for them and we’d like to reiterate in the strongest possible terms their request for privacy,” she said.
Supt Appleford said police were working with local schools and other agencies to make sure support is available.
