TEENAGE car thieves smashed into a car at high speed leaving both the driver and passenger seriously injured.

The two victims had to be cut free from their vehicle in Field End Road, Eastcote, last Wednesday.

The two 15-year-olds jumped out of the stolen green Volvo Estate and fled the scene after crashing into the grey Ford Fiesta at the junction with Woodlands Avenue just after 11am.

Daniella Antoniou, 44, works at Eastcote Travel taxi office outside Eastcote tube station, and was one of the first people on the scene to help the victims, who were in their late teens.

She said: 'The boys in the big car [the Volvo] came flying down the service road. It sounded like a rocket.

"I looked out of the window and they went straight into the Fiesta as it was turning into Woodlands Avenue.

"The ones in the big car all got out and ran away.

"People were fussing around the passenger because he had more facial injuries, but the driver had more internal injuries because his pupils were dilated.

"I was saying: 'Stay with me babe', to keep him going. He needed oxygen straight away.

"I kept him alert because I could see him wanting to go, and he wasn't talking. I kept patting him and just as he was about to go the paramedics arrived.

"The passenger was asking me what happened and I told him not to touch his face because he had a big hole underneath the eye socket and you could see the eyeball underneath.

"Another millimetre and it would of taken his eye out.

"I was shaking when I got back. It was really terrible."

An air ambulance, two ambulances and a fast response car were called to the scene, and a police helicopter and sniffer dogs were used to look for the boys who fled.

* Two people were later arrested for aggravated vehicle taking and a 53-year-old woman was arrested for aiding and abetting. They have all been released on bail as the investigation continues. One of the occupants of the Fiesta was released from the Royal London Hospital late last week, and the other was in a stable condition.
