The family of a charity worker murdered for his iPhone have told of their agony at losing their talented and kind-hearted son.

Two teenagers, aged 17 and 18, have been arrested after Abdul Samad stumbled to his front door and buzzed for help, following the attack by two moped-riding thugs.

As he lay dying on the doorstep of the family home in Little Venice, his parents, Layla Begum and Fazal Miah, comforted him during his final moments.

The 28-year-old as rushed to St Mary's Hospital in Paddington but he died just an hour later after the knife 'went through his heart. Tragically, Mr Samad had been due to marry his long-term girlfriend in 2018. 

His devastated brother, Abdul Ahad, said he received a phone call from his mother to tell him that Mr Samad was dying.

'He loved helping children. That's the sort of person he was. This is a young life gone and such a lovely life,' he told the Evening Standard. 'He was full of energy and loved the kids he worked with. You're not going to find a nice person. It was over a phone, it's just so senseless.' 

Mr Ahad said his brother was able to stagger back to the family home and press the door buzzer before his parents rushed down the stairs to find their son lying on the ground.

He said his brother, who had never been in any trouble, worked for the Dragon Hall Trust charity, helping young people improve their computer skills.  

'He was born in St Mary's Hospital and he's died there. We want these people to go to jail and never come out,'said Mr Ahad. 

He said the parents of Mr Samad, who studied economics at the University of Westminster, arrived in the UK from Bangladesh in the 60s to give their children a better life. Nicole Furre, director of the Dragon Hall Trust, said: 'We are just all devastated by the news.

'We're a very small team here and we're all very shocked and were just trying to process the news.

'He loved his job as a youth worker. He was fantastic with the young people who he was teaching.

'He would do the coding lessons and make apps and he really made it come alive for them all.

'All the children and young people who use the centre will be extremely sad and upset. It is all terribly sad, and such a waste.

'We are making plans about how to manage the children and young people when they hear the news, because he was loved by so many of them.

'They are going to be very upset because they had a close relationship with him.

'He was great and particularly talented whenever there was an issue with a computer or technology, Abdul would know how to sort it out.
