The BBC claimed in June that two people had been questioned after the death of the 11-year-old.
A guy from Lancaster, who is 25 years old, was questioned about charges of child abuse, neglect, drug possession with the plan to sell, and money laundering.
He was given bail and let go.
A 35-year-old woman from Lancaster was also questioned about charges of having drugs with the plan to sell them.
A spokesman for the Lancashire police said that she was freed while the case is still being looked into.
The boy’s family thinks that he died after going along with a dangerous TikTok trend called “chroming.”
