Tributes have been paid to an amateur boxer whose death is being linked to rogue ecstasy tablets.
Richard Carrigan, 24, died and two other men remain seriously ill in Glasgow Royal Infirmary after the three were admitted on Saturday.
Emergency services were called to a house in Waterloo Close, Kirkintilloch, East Dunbartonshire, when Mr Carrigan and his friends, aged 23 and 16, fell ill.
A post-mortem examination has yet to take place but police believe ecstasy tablets may have been involved and have issued a warning.
Mr Carrigan's family said: "He was a loving son, brother, boyfriend and father.
"He was a keen member of Kirkintilloch Boxing Club and was Scottish junior champion. He will be sadly missed."
The drugs concerned are said to have no markers on them and come either as clear capsules containing white powder or in a pink tablet form.
Detective inspector Greig Wilkie said yesterday: ''Whether or not drugs have been involved in this case, I must take the opportunity to stress just how dangerous drugs are.
"We all know that illicit drugs are extremely dangerous and usually contain dangerous chemicals which can have an adverse effect on your health.
''People need to understand the devastating effect they can have, so my advice is don't risk it and report any information to the police.''
Similar warnings were issued last year about "Mortal Kombat" ecstasy pills following the death of 17-year-old Regane MacColl after she collapsed at a Glasgow nightclub.
