A teenage gang, including twin brothers, who stabbed a 15-year-old and beat him with baseball bats “for no apparent reason” have been convicted of the attack.

The gang carried out their “a brutal and callous” attack outside of a birthday party in Brixton.

The following six teens were found guilty of GBH with intent after the victim ended up in hospital with multiple stab wounds and a punctured lung and stomach:

Taylor Joseph, 18, of Ewen Crescent, Brixton;

Brandon Joseph, 18, of Ewen Crescent, Brixton;

a 16-year-old male from Penge;

a 17-year-old male from Streatham;

a 16-year-old male from Brixton;

a 16-year-old male from Clapham.

The gang approached the victim when he was playing outside with friends on March 31, where they were attending the birthday party with family members and small children.

The gang were armed with baseball bats, poles and knives, and some of them were wearing face masks.

Most of the victim’s friends ran back into the address but the victim tried to flee and was chased.

The gang caught up with the victim, punched him, tripped him up, and repeatedly struck him with their weapons.

It wasn’t until a nearby driver sounded a car horn did the attackers flee the scene and the teenage victim was able to escape back to the party address.

He needed two operations, spent ten days in hospital, required continuous rehabilitative treatment in the months afterwards and still has nerve damage in his shoulder.

Police discovered the knives used in the attack at a different nearby party with over 120 teenagers.

After screening the party attendees, taking witness statements, and performing forensic investigations, eight people were charged in July 2016, each of them between the age of 14-16 at the time of the attack.

After a six-week trial, on February14, six of the suspects were unanimously convicted at Inner London Crown Court.

Danni Wilgoss, of Brixton CID, said: “This was a brutal and callous attack that, were it not for the quick actions and expertise of paramedics and the aid from members of the public, could have resulted in the loss of a teenage boy's life.

“Those who carried out this attack did so for no apparent reason other than the victim was in the wrong place at the wrong time. They took shelter in numbers and showed a total disregard for the safety - and life - of the victim.

“An investigation is only ever as good as those who step forward to assist and I want to pay tribute to the witnesses who were extremely brave to provide evidence.

“I also want to pay tribute to the victim who has shown remarkable bravery and tenacity since the incident. His positive attitude is admired by my colleagues and I alike.

“This case demonstrated that the local community will not stand for such violence. It was a painstaking investigation which shows that the Met is committed to vigorously pursuing anyone who commits such acts.”
