Joshua Molnar served eight months in prison after stabbing his friend to death after a row.
Yousef Makki was stabbed in the heart by Molnar with a flick knife in March 2019 in the upmarket village of Hale Barns in Cheshire when they were both aged 17.
Molnar claimed self-defence and was cleared of murder and manslaughter by a jury, but admitted to possessing the knife which caused Yousef's fatal wound and perverting the course of justice.
