Pretana Morgan is helped at the scene by a friend

A grieving mother yesterday urged teenagers to 'stop, please' and 'make the most of your one life' after her own 17-year-old son was gunned down on London's streets on Saturday night.

Rhyhiem Ainsworth Barton's mother Pretana Morgan, 38, said she 'couldn't have asked for a better son'.

The teenager - who rapped under the name GB - has been named by his mother who said he had 'had so much potential' for the future.

She added: 'My son was a very handsome boy.

'This is not life. My son's a good boy,' she said.

'He was going to do 13 subjects at school before they kicked him out.

'He was a bright boy.'

His devastated mother told how she found her fatally wounded son surrounded by armed police early on Saturday evening.

'I was sat in the park and someone said they heard the Peckham boys were around.

'I came looking for Rhyhiem and a girl said she saw boys running up and down.

'I saw a boy on the floor, it was my son on the floor with police with guns over him.'

She claimed he was targeted by thugs from a gang who terrorised the Brandon Estate in a silver BMW armed with a shotgun on Friday and Saturday night.

Talented rapper Rhyhiem had previously been stabbed a the gang in May 2016 and she was so worried she sent him to live with relatives in Jamaica, where she was born, for his own safety.

He only returned back to London in February.

She continued: 'We do not need this.

Ms Morgan pictured said she 'couldn't have asked for a better son' who was 'trying to make a difference' by learning to work with children

'We cannot be doing this all the time, teenagers you need to stop please.

'Enjoy your life, your youth, get knowledge in your head, get wisdom and knowledge.

'You only have one life, you better make use of it.

'They shot him from a car, there will be no forensics.

'I do not know when I am going to see my son.

'I need to see my son as soon as possible I need to hold him, my handsome boy.

'There is no gang round here, we live as a family.

'He was just trying to focus and trying to be an architect, he was not a bad child.'

She criticised the police, saying: 'We're not being protected because of the police. The police are the ones putting us in danger.'

Rhyhiem's best friend Abigael Adeoye, 17, said: 'We were friends from when we were young at primary school.

'He was really bubbly, he used to message me and say 'Abigael come and see me'.

'I should have told him to stay at home yesterday.'

Ms Morgan brought with her to the scene her son's driving license, old teeth, birth tag and a picture of the two of them together

Mr Barton's godmother Lacey Main told how he had been chased by a gang armed with 'swords and machetes' before being sent to Jamaica 'for his own safety'.

During the ambush the teenager ran to his godmother's home where the gang stood outside, demanding she send him out.

She said hey screamed: 'We want Rhyhiem! We are going to kill him. Send him out!'

A year later aspiring architect Rhyhiem was fatally shot in the chest just weeks after returning to the Brandon Estate in Kennington, south London, where he lived with his mum and six-year-old sister.

His godmother, Lacey Main, said: 'This has been going on for three years - they come and stab people randomly.

'About a year ago they chased him into my home and they broke down my gates and they were standing there with machetes and swords.

'They said 'We want Rhyhiem! We are going to kill him. Send him out!'

She added: 'I will not send a child out for a killing.'
