Gulam Chowdhury, left, stabbed his love rival Mohammed Afzal, right, 20 times at an east London cab office . The Old Bailey heard that Mr Afzal had threatened to show intimate pictures of Nargis Riaz, to her Imam father . The Old Bailey heard that Ms Riaz had been involved in a relationship with Chowdhury and Mr Riaz for several weeks before the murder on March 24, 2014. Her parents were unaware she was friendly with either man. Chowdhury told Ms Riaz, a second year law student at City University, the attack was justified in Islam claiming: 'Cut the neck of the man who eyed up his wife.' Later he reassured her: 'Don't worry little angel, it's me who's a psycho not you.' Chowdhury showed no emotion today as a jury of seven men and five women found him guilty of the murder of Mr Afzal, 22, on March 24 last year. Riaz, who was also standing trial for murder, faces a retrial after the jury failed to reach a verdict after 21 hours and 37 minutes’ deliberation. Co-defendant Muhammed Khan, 23, was acquitted of assisting an offender. The court heard Ms Riaz had been dating both Chowdhury and Mr Afzal in the weeks before the murder, but kept both relationships from her strict parents. Dramatic CCTV footage showed masked Chowdhury storm the E20 minicab company in Stratford Broadway, east London on March 24 last year. Muhammad Khan, pictured, was acquitted of assisting an offender at the Old Bailey . He vaulted the counter armed with a carving knife as Riaz was stood outside during the frenzied attack. Detectives investigating the murder found a series of texts from Chowdhury to her in the weeks leading up to the attack. In one message, Chowdhury repeatedly asked Riaz if she wanted his rival dead and told her: ‘No one hurts Nargis and lives’. Having converted to a strict form of Islam while held in an immigration detention centre, Chowdhury regularly quoted the Quran in his messages to Riaz. He told her: ‘I’m going to sort this out and sort it proper, I will use the flame from my ancestors to burn the world of this scum.’ He also wrote in another message that his ancestors were ‘fearless lions that would kill for honour’. Chowdhury claimed killing was justified by Islam and included a passage from the Quran which said: ‘Cut the neck of the man who eyed up his wife’. In another text he wrote: ‘I need to kill someone’. Prosecutor Sandip Patel QC said Riaz was treated ‘like a Queen’ by Mr Afzal, but had threatened to show intimate pictures to her parents during a ‘difficult phase’ in their relationship. ‘They had known each other before and had been boyfriend and girlfriend in the past but Mr Afzal was unaware Miss Riaz was at that time seeing Mr Chowdhury,’ he said. Riaz, who also worked at Primark in Hackney, claimed she did not believe Chowdhury would carry out his threats. Chowdhury, from Barking, denied, but was convicted of murder. He was held at Broadmoor secure hospital prior to the trial, and was initially deemed unfit to plead due to mental health problems. Riaz, also from Barking, denied murder. Khan, from Dagenham, Essex, denied assisting an offender between March 24 and March 26, 2014 and was acquitted. Speaking outside the court, Detective Inspector Euan McKeeve of the Homicide and Major Command said: 'Gulam Chowdhury carried out a ferocious assault on Mohammed Afzal. The level of violence used was shocking and ensured that Mohammed would not survive the attack. 'Whatever Mohammed's motives were for the actions he took in attempting to maintain his relationship with a woman, he did not deserve to be murdered. 'It is thanks to the thorough and meticulous work of my officers who have worked tirelessly since Mohammed's murder that we have managed to prove Chowdhury planned, and then executed, this vicious assault which ended in the savage murder of a young man.' Eyewitnesses described how Chowdhury was wearing a distinctive 'JD Sports' shoulder bag shortly before the murder. Officers then were able to place him at the scene using CCTV footage and mobile phone cell data analysis. Chowdhury is due to be sentenced on May 1.
