Queensland's Crime and Misconduct Commission (CMC) will oversee an investigation into the death of a teenager run over by a car after he was arrested by police.

Andrew Dornen, 16, was left lying on a busy road in Ipswich, west of Brisbane, on Saturday night.

He was rushed to hospital with massive head injuries but did not recover.

Police arrested the teenager after receiving reports of a man wielding a machete in the suburb of Brassall at about 11pm (AEST) on Saturday.

He was reportedly unarmed when arrested by plain-clothes police officers.
