15-year-old, Euan McNamara collapsed in Browns at Liverpool ONE restaurant following an afternoon of shopping on Saturday, October 22.
Despite immediate medical intervention by off-duty medics, the teen died later at Royal Liverpool University hospital.
Merseyside Police said his death is not believed to be suspicious.
In a tribute to Euan, his parents Michael and Sian McNamara, said they hoped to find out the answers as to why their son had been “cruelly taken away”.
“On Saturday teatime, after an afternoon’s shopping, we were at Browns restaurant in Liverpool as a family with our son Euan, daughter Megan and close friends when Euan unexpectedly collapsed. Despite immediate medical intervention by off-duty medics, Euan later sadly passed away in hospital.
“Euan was a much-loved son, brother, grandson, nephew and friend. He was studying for his GCSE exams, a keen rugby player, cricket player and LFC Supporter, regularly attending games with family and friends.
“Euan was loved and adored by all who knew him and his death has left a massive void in all of our lives. He was a handsome, loving, caring boy with an infectious personality that touched everyone he met. We are devastated by what has happened, and hope that in the forthcoming days we will find out why Euan has been cruelly taken away from us.
“We as a family please request that our privacy is respected at this time.”
