A student in Uganda chased a murderer until he dropped the head of the victim he'd just decapitated.

The murderer put it in a bag and ran off. The student chased him for more than a mile until he dropped the head.
The murderer has disappeared, local media report.
Regional police commander Ahmed Wafuba said: "It is very rare that an assailant kills somebody and carries away the parts."
