Two teenagers shockingly fist bumped each other and chuckled just minutes after they tried to stab an innocent man to death in Sheffield city centre.
The giggling men, who appear entirely unfazed by their murder attempt, were arrested by police armed with tasers moments later.
Ramaray Treasure, who was 17 at the time, and Leon Sykes, 19, launched a ‘brutal and random’ attack on innocent man during the early hours of March 9 last year, police said.
They stabbed their victim multiple times before being stopped by a brave passer-by.
The teenagers, dressed in black hoodies, jeans and white trainers, then strutted down the street casually before fist bumping each other multiple times, while clinching knives in their hands.
The full attack was caught on CCTV and the pair were tracked before police armed with tasers intercepted them.
Treasure tosses his knife into the air in an attempt to throw it over a nearby wall as police arrived.
Both men were jailed after pleading guilty for attempted murder and possessing an offensive weapon in a public place on Friday at Sheffield Crown Court.

Ramaray Treasure, 18, from Sheffield, was handed a 12 year prison sentence.
While Leon Sykes, from Stocksbridge, was jailed for 13 years and eight months.
The victim said he has suffered from anxiety and depressive episodes following the attack and he is still in pain.
He said his career has been halted as it happened just six months after he finished his masters degree.
Detective Constable Gareth Rees, of South Yorkshire Police, said: ‘Treasure and Sykes launched an horrendous and random attack on a victim who they chased through a busy city centre street and stabbed multiple times in full view of passers-by and a businessman operating a food truck.
‘The attack was interrupted by an incredibly brave member of the public who rushed to the man’s aid. The victim suffered extremely serious injuries which were initially considered to be life-threatening, and he is still dealing with the effects of the attack to this day.
‘Treasure and Sykes were tracked as they made their way through Sheffield. At one point, they were seen laughing between themselves. That laughter soon stopped as they were greeted by our officers at Pound’s Park.’
