TWO more teenagers have been arrested in connection with the fatal stabbing of vulnerable Dean Mayley in Greenford.

The pair, aged 17 and 18, were detained on suspicion of murder after handing themselves in to police on Monday.

Earlier in the day, two others - both charged with murder - appeared at Willesden Youth Court.

Dean, 24, died in hospital after the attack in Ruislip Road, Greenford on 7 February.

The Met Police said the new suspects had been arrested on suspicion of murder and were being held in custody at a north London police station.

The two 17-year-olds already charged with Dean's murder are also accused of conspiracy to rob and possession of an offensive weapon.

They were remanded in custody after their court appearance, ahead of a bail hearing at the Old Bailey on Wednesday.

Dean, from Northolt, was on his way to see his uncle when he was attacked.

He had a disorder which left him with moderate learning difficulties and a mental age of nine.

A post-mortem gave the cause of death as a single stab wound to the chest.
