TEACHERS and friends have paid tribute to the Saltash student who died after collapsing in the toilets at town's Cornwall College campus.
Charlie Alford, 16, was pronounced dead at Derriford Hospital in Plymouth, on Wednesday last week after his body was found by staff.
Police said they were not looking for anyone else in connection with the incident but were unable to comment on the possible cause of death.
An inquest was opened and adjourned by the coroner in Plymouth on Monday.
The cause of the death was still "unascertained".
The full inquest will be held at a date to be set.
Friends of the Landrake student paid tribute to him this week.
Alana Breakingbury called him "a great friend", adding: "I don't know anyone that didn't like you but you're now in a better place.
"You left your stamp on the world forever."
On one of several Facebook memorial pages dedicated to Charlie, Fraser Watt wrote: "You were the nicest, funniest person you could ever meet."
Teachers also paid tribute to the student, who had only recently started at the college.
In a statement, Jan Langley, Charlie's lecturer at Cornwall College, Saltash, described the teenager as "a cheeky charmer who you couldn't help but like".
The statement added: "He was so popular with his classmates and they'd all really got to know each other well in the few weeks since he started at college. It's such a sad loss."
Cornwall College principal Dave Linnell said: "We are deeply saddened by this tragedy.
"Our thoughts are with Charlie's family and friends.
"We are supporting students and staff at this difficult time."
A Cornwall College spokeswoman said counsellors had been offering support to students and staff affected by the tragedy.
