Ive just been interviewed by an American TV station and they said Im celebrity over there. Theresa said she was driving home with a friend after attending an art group at the Salvation Army in Barnstaple on Thursday afternoon. Wed also done a bit of shopping but when we were driving home through Muddiford, there was a car in front driving really erratically. He went over the white line a few times and hit the wing mirror of a car coming the other way so I decided Id report him to the police when we got home. I asked my friend to find the number for Barnstaple police on her phone and she used the phone app Cortana to find the number. I just called the number that came up and thats how I got put through to police in Barnstable.Global coverageA recording of her hilarious conversation with Barnstable police officer Mark McWilliams was posted on YouTube by Massachusetts news website HyannisNews.com.
