Paramedic Coleen Johnson was on her way to work heading south on the M5 shortly after 5.30 am. She says she was close to the Ottery turn-off when she saw a man walking towards her in the highway lane.
Fearing that she was going to hit him, she says she slowed down.
He then threw a brick at her car window, cracked window, and she was hit on the right side of the head.
Johnson says luckily she has only sustained cuts on her face and bruises after the incident.
I was very lucky. The brick hit the pillar of the car before it came smashing through the window so I think that took a lot of the force out of it.— Coleen Johnson, paramedic
I was in the left hand lane and I saw a man walking in the middle of the road towards me in the right hand lane. So I slowed down, and I thought is he drunk. And then he didn't move.— Coleen Johnson, paramedic
She says when she was about 50 metres away from him, she started to hoot.
And when I hooted, I saw his arm come up in a bowling action, and the next thing I knew, the brick was through my window and had hit my head.— Coleen Johnson, paramedic
I could feel that I was bleeding, so i just put my foot down and just drove. i didn't look back.— Coleen Johnson, paramedic
She says one of her ambulances met her on the way and took her to hospital.
Johnson says if she was in a situation like that again, she would stop, reverse and drive in the opposite direction, or drive across the grass island in the centre of the highway and get away.
It was the last thing she expected to happen, she says, and it does make one reconsider what to do when something like that happns.
