A white father out celebrating his daughter's birthday was brutally knifed to death in front of his horrified family just because he asked if a crying black child was alright

Alan Smith, 63, was stabbed at least five times as he sat with his partner, daughter and son-in-law in a cafe in east London. The black killer, Matthew Quesada, became enraged when Smith approached him in the BB Cafe to ask if his young daughter, who was crying, was okay. Quesada responded "What's it to you? What's it got to f****** do with you?" before storming out of the cafe. Humiliated and angered by what happened Quesada, then aged 25, ran to his girlfriend's home to drop off the girl and grab a weapon. With a knife concealed up his sleeve, he then raced after the family as they entered a second diner - the Roma cafe - where they had gone to eat to avoid any further trouble. It was there that Quesada launched a frenzied and wordless attack, stabbing Smith in the head and body. As Estelle Jenkins tried to get between her father and his attacker, Smith struggled up from the bolted down table before falling to the floor where he kicked out in a vain attempt to stop the onslaught. Quesada only fled when the victim's son-in law Mark Jenkins threw a chair at him, halting the attack, as Smith's horrified partner Denise Facey looked on. As Smith's life ebbed away an air ambulance doctor had to perform emergency heart surgery on a cafe table that formed a make-shift operating table. He was flown to hospital where he died from his wounds, three of which were fatal.
