A family were left shocked and in tears after they were violently rammed by police.
Pregnant mother of two, Shiri Rahman, was in the car with her young son who had just been to hospital, as well as her husband and sister.
Bradford Police believed the vehicle belonged to criminals after they used cloned plates for an armed robbery.
'It all happened in a flash,' said Mrs Rahman, 34. 'My husband slowed down to let the car behind us pass. It went in front of us and braked, forcing my husband to stop.
'Another car pulled up beside us and then a third one came up behind and hit us in the back. I was jerked forward and then back in my seat.
'We were barricaded in and the car was surrounded by police, there must have been eight or nine of them. I couldn't see any guns, but the police told us the car that hit us was an armed response vehicle.
'They took my husband out of the car. We couldn't understand what was going on. I was shocked. Terrified wasn't the word for it.
'I started to have an anxiety attack. I was finding it difficult to breathe and was panicking. My son was crying in the back.
'You think stuff like this happens in the movies. You don't expect it to happen in real life - even less be in the middle of it.'
The family had taken five-year old Mohammed Eesaa to Bradford Royal Infirmary after he had developed a fever. They left the hospital in the early hours of the morning and headed home.
Abdur Rahman, 35, was taken to a police vehicle while checks were made by police.
'The officer explained they had information the vehicle had been involved in an armed robbery and they had to take full precautions to make sure the robbers did not get away, which is why they had to do what they did,' added Mrs Rahman.
Detective Superintendent Jon Morgan, of Bradford District Police, said: 'At 11.59pm on Sunday, February 1, police received information about a vehicle which was believed to have been used in an armed robbery outside of West Yorkshire.
'Following inquiries, a vehicle bearing the suspected number plate was sighted in Ingleby Road, Bradford.
'In accordance with the information received armed officers were deployed to stop the vehicle safely, which resulted in a minor collision.
'Ambulance crews were also requested to attend to a pregnant woman who was inside the vehicle.'
Mrs Rahman claimed the paramedics were unsympathetic and declined to treat her family.
'We are aware of the incident that took place on Ingleby Road in Bradford,' said Ben Holdaway, of Yorkshire Ambulance Service NHS Trust.
'We are keen to speak to the family directly and would urge them to contact our Patient Relations team on 0345 122 0535 so that we can look into this matter further.'
