Two gang members who gunned down an innocent teenager after mistaking him for a rival have been jailed for a minimum of 30 years each.

Student Nana Darko-Frempong, 18, was blasted in the stomach and face just for being “in the wrong place at the wrong time.”

His killers were members of the notorious Roadside Gs street gang, based in Camberwell, south London. They assumed he was a member of the rival TN1 - or Trust No One - clan because he lived on an estate in that gang's Tulse Hill heartland.

Christopher Gabriel, 25, used a sawn-off shotgun for the drive-by hit on June 6, 2011, while another man, also 25, who cannot be named, fired at the victim with an automatic pistol.

Other members of the gang then burned the stolen Ford Focus used in the drive-by hit so the killers could escape justice.

But they were tracked down after an associate called police and identified them.

In a statement read to the court, Nana's father Roddy said of his son: “Despite his non-participation in gang culture and the evil they generated, their evil came to him.

“For them, his life had no value. It was a cruel and despicable act, aided and abetted by cruel, horrible people.”

Christopher Gabriel, 25, and a second man, also 25, who cannot be named, were convicted of murder following a three-and-a-half month Old Bailey trial.

Judge Nicholas Cooke jailed them each for life yesterday and ordered them to serve a minimum of 30 years behind bars.

He said: “This was a gang-organised shooting of a wholly innocent teenager. There has been no indication of genuine remorse of the part of either of you. There is little purpose in wasting any further words on you.”

Romario Henry, 21, along with two men, aged 27 and 24, who cannot be named were convicted of perverting the course of justice and each jailed for eight years.

Judge Cooke told them: “You three knew that the car which was burned out had been used in a shooting that was likely to have been fatal. You were in fact by destroying this car approving of their act. Indeed, even now, although you have long since become aware of just how dreadful that shooting was you have shown not one shred of remorse. Your conduct was intended to make bringing the killers to justice impossible.”

Al Daniels, 22, was convicted of firearms offences and will be sentenced next month.

A seventh defendant, Sachia Clarke, 22, was cleared of six firearms charges but jurors were unable to reach a verdict on a further two counts.
