Three men have been convicted of carrying out strangulation robberies on two women in St John’s Wood and Westbourne Park.

Carlton Walker, 35, was traced through the DNA he left on his victim’s face after he placed his hand over her mouth to stop her from screaming while he robbed her on the driveway of her home in Clifton Hill.

The 58-year-old woman had just got out of her car when Walker grabbed her from behind and placed his hand over her mouth.

She was then strangled until she passed out in September last year.

When she regained consciousness she was punched in her face and head while her earrings, rings and bangle were ripped off her.

Walker, and an accomplice who has not been identified, fled the scene in a car after their victim’s screams alerted passer-bys.

In a separate yet identical attack a 40-year old woman was robbed by two men on the driveway of a property in Westbourne Park on March 1 this year.

One of the robbers held his hand over her mouth while the other removed a £11,000 ring from her hand.

The pair left in a hired car which was later traced to Junior Morgan, 37, from Ladbroke Grove.

When Morgan and his accomplice Dean McFarlane, 37, from Fulham, were arrested they were coincidentally wearing the same clothing they wore on the day of the robbery.

Detectives also recovered paperwork to prove they Morgan had rented the car spotted at the scene.

Morgan had sold the stolen ring to a jeweller in Hatton Garden hours after stealing it.

Detectives recovered the ring but it had been broken down.

Last week at Southwark Crown Court, Walker was jailed for 11 years and nine months.

Morgan and McFarlane will be sentenced on August 30.

All three admitted robbery.

Detective Sergeant Vince Abrahart, from Westminster Crime Squad, said: “These men committed extremely violent robberies on unsuspecting women who they specifically targeted so they could steal high value jewellery.

“They were ruthless and showed no consideration for the victims who as well as losing personal items, were left highly traumatised.”

The hunt continues to find Walker’s accomplice.
