A mother and eight-year-old son were the victims of a "terrifying" police car chase through St Paul's Cray.

Sam Seymour, of Chelsfield Lane, Orpington, was driving her Volkswagen Golf down Sandy Lane on Friday (May 9) evening at 6.30pm.

The 28-year-old was in the car with her son, Charlie, and sister Claire, 27, when suddenly, out of nowhere, a car rammed into the back of her vehicle.

She said: "It kept ramming us until it got past us. It must have rammed us about four or five times.

"We were absolutely terrified. We were so scared, we didn't know what was going on.

"My son was screaming and crying, we were all completely shaken. It was like something out of a horror film."

Mrs Seymour, who was left shaken at the side of the road, says the car was being chased by two police cars but none of the officers stopped to see if she was OK.

She said: "I'm really angry because the police didn't even stop.

"I suffered severe whiplash and muscle injuries in my right arm and hand.

"My son suffered whiplash in his back, my sister who was also in the car also suffered from whiplash."

She called 999 requesting police and an ambulance, but an ambulance never showed up at the scene. 

She said: "We called for an ambulance and they called me back 40 minutes later to tell me they were too busy.

"I've stood on the road side with my son for 40 minutes waiting. That's totally out of order - he could have been seriously hurt.

"My dad had to drive us to the hospital. I feel really let down."

Mrs Seymour added: "The man who did it - I hate him right now. 

"I got in my husband's van after the incident and I had a panic attack.

"My son hasn't been in a car since and he's been very poorly since it happened."

A London Ambulance Service spokeswoman said: "We were called at 6.41pm on Friday to reports of a road traffic collision on Sandy Lane.

"We rang the caller back at about 7.10pm to get further details of the patient's injuries. The caller confirmed the patient had a sore back and did not have any serious bleeding.

"We advised that an ambulance would be with them as soon as possible but we were unable to confirm the exact time as we were very busy.

"The caller then said they would make their own way to hospital."

A police spokesman said: "A car was chased through St Paul's Cray by police before crashing into another car and a lamppost.

"On Friday police on patrol in St Paul’s Cray attempted to stop a Volkswagen Golf at around 6.30pm.

"The car failed to stop so police pursued it.

"The car then collided with another Volkswagen Golf in Sandy Lane, before it collided with a lamppost in Broom Avenue.

"The 23-year-old male driver of the vehicle that failed to stop was arrested on suspicion of dangerous driving and taken to a south London police station.

"He has been bailed until June 11."
