A man who was arrested after the death of a mother and son in north London has been released with no further action.
Police and paramedics found a 37-year-old woman and a five-year-old child with stab wounds at an address in Brookside South, Barnet, on Tuesday. Both were pronounced dead at the scene.
They have now been identified as Yi Chen, a Chinese national, and her son Xing Duan Yuan, who was born in the United Kingdom and had a Chinese passport.
Scotland Yard said a post-mortem examination on the mother had provided ‘important new information as to the nature of her injuries’.
Detective Chief Inspector Claire Hine said: ‘Following the post-mortem examination, the 37-year-old man who had been arrested in connection with the deaths has been released without further action. Nobody else is sought in connection with the two deaths.’

They also left a cardboard sign with the toys which read: ‘There is no evil and suffering in heaven! Rest in peace!
‘Thank you for the happiness. You will be remembered.’
A friend who lives close to their former address told MailOnline today: ‘Yi was a lovely lady, a doting mother. She was perfect.
‘She would play with her two sons in the area outside the house quite often.
‘That’s when I saw her the most, she stayed inside a lot of the time, but when I did see her, she was outside having fun with her children.

‘I’m shocked this has happened. Her youngest son was Duan Duan. He was a cheeky little boy but full of character, even at the young age he was when they lived here.
‘My heart goes out to their poor family.’
Ms Chen and her husband, 37, who is Director of Data Science at digital TV firm FreeWheel, have been living in the UK since 2010, having moved here from Beijing.
They are said to have been a quiet family who did not interact much with their neighbours at their current address in Barnet.

‘Within minutes there were police and paramedics everywhere. An air ambulance landed in the school playing field nearby.
‘The police were searching my neighbour’s house. A man was later taken away by officers. However, he was not in handcuffs and there did not appear to be any blood on him.
‘The people in the house are a quiet couple, who keep themselves to themselves. I’ve not spoken to them very much at all.
‘The husband worked from home a lot of the time and I don’t know what his wife did. They had two boys. The oldest was at school when all this happened.
‘This is so shocking because this has always been a peaceful, safe area.’
