Oxford Street stabbing: Family pays tribute to 'loving son'
The family of a teenager who was stabbed to death in London's Oxford Street during the Boxing Day sales have paid tribute to him.
Seydou Diarrassouba, 18, was stabbed after a fight began in the Foot Locker sports shop near Bond Street Tube station on Monday.
His family praised the "loving son and brother" who was "snatched away".
The tribute came as police raided the homes of 20 suspected gang members to "quell" related tensions.
Police targeted suspected gang members in Merton, Wandsworth and Southwark.
'Respectful and charismatic'
Officers made 17 arrests, for offences including grievous bodily harm, robbery, intent to supply drugs, burglary, forgery and handling stolen goods. A large amount of cash was seized.
Commander Mak Chishty said: "We were aware of rising tensions in the wake of the murder.
"Having monitored the situation closely, including various comments on social networking sites, we felt it vital we take robust and prompt action in order to pre-empt any potential future violence."
Mr Diarrassouba's family said in a statement: "A simple shopping trip has turned into a complete nightmare for our whole family.
"Whoever took his life took our backbone away. Seydou kept us upright and now we feel weak as we have lost a very special part of us."
It continued: "Life seems meaningless without our special son, brother.
"All we can say is why? He had so much consideration for others.
"We want Seydou to be remembered as the loving, down to earth, respectful and charismatic young man he was."
A number of weapons were found at the scene of the attack.
