Four thugs have been jailed after a man was repeatedly stabbed with a 17-inch blade on a train from Grove Park to St John’s. 

On November 21 last year at about 7.30pm they boarded a Southeastern train at Grove Park station. 

At Hither Green station a 19-year-old man boarded the train and was confronted by the four. 

Rowan Jones and Jahvarn Warren grabbed the victim’s coat and slapped his face while Kumarl Best produced a huge knife and stabbed him multiple times. 

The victim fell to the floor but the group continued their attack, kicking and punching him whilst Rowan Jones filmed it. 

The four then retreated to their seats on the train at which point the victim hobbled to the next carriage where he collapsed onto a seat holding his thigh where he had been stabbed. 

The group then ran off the train at St John’s while the victim limped off and was helped by members of the public. 

He was taken to hospital where he was treated for a large stab wound to his thigh, a smaller wound to his thigh and several defensive wounds to his hands. 

Investigating officer DC Danny Nelson said: “This was a brutal and senseless attack and the victim was fortunate not to sustain further injuries. 

“While none of the four revealed the reason for their actions, the frenzied nature of their onslaught leaves no doubt that their intention was to cause serious injury. 

“There is absolutely no reason to carry a deadly weapon like this in public, unless they mean to endanger life.” 

The four were arrested in the coming days and the 17-inch blade was found at Best’s home, still covered in blood.
