Hull combat knife murder: Agustin Sula jailed
A teenager who stabbed a man to death with a 20cm-long combat knife in a Hull street has been jailed for a minimum of 18 years.
Agustin Sula, 18, struck Mateusz Szleper seven times in the chest.
Mr Szleper, 21, had been collecting food from a takeaway when Sula followed him and attacked him near Spring Bank on 14 February, Hull Crown Court heard.
Sula's brother, Ermal, 24, of no fixed abode, was jailed for four years for assisting an offender.
Sentencing him, Judge Jeremy Richardson QC said Sula had "not exhibited a shred of remorse or contrition for your vicious conduct".
He added: "You were impetuous, volatile and invariably angry that night."
The court heard the Albanian national, who was described as being fascinated with knives, hid the blade in bushes after the attack and washed his clothing.
Mr Szleper was a stranger but Sula had thought he had bumped into him earlier that evening.
He was described by a witness as being in a "very volatile state of mind" afterwards and went to search for Szleper.
Sula, also of no fixed abode, was convicted of murder last month following a trial.
