A man and a woman have been arrested in Wolverhampton on suspicion of murder after a toddler died from a heroin overdose.
They are currently being questioned at a police station in the West Midlands.
Both were detained in connection with the suspected murder of 23-month-old Daniel Jones.
He was pronounced dead at the scene by paramedics who responded to a call to a house in the Penn area of the city at 6.15am on Tuesday, May 29.
Detectives from West Midlands Police launched an investigation to establish the circumstances surrounding the child's death, which was initially treated as unexplained.
However, the results of recent forensic tests showed the child's death was caused by a heroin overdose.
