16 year-old Taha Soomro from Grangetown, Cardiff, died following a medical epsiode at the amusement park late on Friday afternoon.
Detectives have again urged the public to avoid speculation on social media while an investigation continues to establish the exact circumstances surrounding Taha's death.
A 15 year-old boy from Grangetown arrested on suspicion of assault has since been released on bail pending further inquiries.
