Friends of missing Jordan Cobb returned to school yesterday for the first time since the 16-year-old's "heartbreaking" disappearance.
Police, Coastguard and RNLI crews continued the search operation as students returned to Stoke Damerel Community College for the first time since Jordan jumped from a ferry crossing the River Tamar on New Year's Eve.
School principal Carol Hannaford said: "We are all so very sad that Jordan hasn't been found yet. The uncertainty of this situation is truly heartbreaking for his family and friends. Our continued thoughts and prayers are with them at this terrible time.
"We will be talking to Jordan's friends at the school about what they would like to do in the coming days and weeks, and they will decide what happens.
"Jordan's circle of friends is very wide, not only from our school, so it's important we take that into account.
"Young people have access to a range of support services, which are being co-ordinated through the school in partnership with the council."
A Facebook page set up in honour of Jordan continues to attract hundreds of messages from well wishers.
Abby Norman wrote: "All of you back at school today, thinking of you, try your hardest to smile for him, sure he would rather that than your tears. What lovely friends he has."
An online fund set up by Jordan's friends has so far attracted more than 100 donations and raised more than £1,270, which will be given to Jordan's family.
