A couple are searching for the good Samaritan who went out of his way them in an emergency so they can say thank you.

Parkinsons sufferer John Edwards and his wife Glynis, who has trouble walking, were on the way back from an appointment at Queen Mary's Hospital in Sidcup, when they stopped at Tesco in Edgington Way to do some shopping.

As they made their way back to their car with their shopping in the rain, Mr Edwards, 73, had a fall.

Mrs Edwards said it was a nasty tumble.

She said: "He feel to the floor, into a puddle. I wasn't going to be able to get him back up on my own, I am disabled as well. We were both shaken.

"We needed somebody to help, because he was still on the floor. I couldn't get him back up."

As the couple struggled, a good Samaritan stopped his car and rushed to their aid.

The kind man helped Mr Edwards up and sat with them, reassuring them it would be ok.

Mrs Edwards said: "He was so very nice. He asked if we needed to go to the hospital, he offered to drive our car home if we felt we couldn't.

"He sat with us for at least 10 minutes, and he even offered to drive behind us to make sure we got back safely."

Mr and Mrs Edwards, who live in Crook Log, moved to Bexley in 1981 from Wales.

The couple, who have been married 30 years, were too shaken to catch their hero's name, but really want to say thank you.

Mrs Edwards said: "We really want to say thank you, because I don't know what I would have done with out him. They were only looking for a parking space and they came rushing out their car.

"He was so nice, and we are so grateful. We hope he reads this and sees our thanks, because we appreciate it so much. His help was invaluable."

After the fall at around 3pm yesterday (October 26), Mr Edwards, who worked for the Salvation Army, went to hospital today where he was told he has broken his big toe.

He also has a swollen foot, and is still a bit shaken.

His wife said: "Having Parkinsons doesn't help but he is still shaken from it. It was quite the ordeal for both of us, it was really lucky this man was here."
