TEENAGE gun-wielding carjackers are behind bars after police tracked them down by their DNA.

Dongo Owoola, aged 19, of Knee Hill Crescent, Abbey Wood and Nanguy Gbedje, aged 17, of Samson House, Maxey Road, Plumstead, brought terror to Greenwich last year through a series of violent robberies.

Between November 6 and November 11 they carried out three gunpoint robberies across the borough and stole a Vauxhall Astra, a Vauxhall Corsa and a Fiat Ulysses.

But the yobs, part of a larger gang, gave away their identities two days after snatching the Ulysses.

On November 20 it was used by the pair during a street robbery in Charlton, a petrol theft in Islington and the knifepoint robbery of a BMW owner in Hackney.

The vehicle was later abandoned, giving Greenwich robbery squad officers the chance to take fingerprint and DNA samples.

Other vehicles taken by the pair were dumped in Abbey Wood - giving further clues to their identities.

At Blackfriars Crown Court on June 6, Owoola and Gbedje, also know as Bello and Rudy, were found guilty of conspiracy to commit armed robbery.

On September 4, Owoola was sentenced to 13 years and Gbedje to 10 years.
