Mum runs off with incest son

A mother has run away with her teenage son after being reported to police for having sex with him.

The unmarried woman, 38, fled her home with the boy she had given up for adoption years ago after being reunited with him recently.
 
Now 18, the boy and his mother are on the run after declaring they are in love and want to have a family together.

They hope to set up home hundreds of miles away where they are not known and live as husband and wife.

Yesterday, the woman's distraught sister vowed never to speak to her again.

She said: "She is no longer my sister. It's was so awful to see them doing that I can hardly believe it."

The sister said: "They would not stop having sex even after they knew I was there. I had to pull him off her. At first I thought she was being raped by him!"

Two weeks ago the mother's sister found them having sex on a sofa and threatened to call police if the son did not leave.

The mother had had no contact with her son since she gave him up for adoption, along with his sister, in 1992.

She kept only her eldest daughter as she moved about the country before settling down with a long-distance lorry driver. Four months ago, the siblings were reunited via social networking site Bebo and they moved back home to be with their mother.

The mother's sister said: "From the start, my sister and her son got on brilliantly. When they first met he said, 'You are quite nice looking for being my mum'.

"When we had a party they sat on the stairs all night with their arms around each other and crying. I thought it was because of the adoption thing."

The woman's sister said: "There were signs. She always tried to be alone in the house with him and slimmed down from a size 16 to 10.

"It was never easy for her because her husband was away such a lot."

"This whole thing is ripping us apart."

Experts say genetic sexual attraction can occur between close relatives who are separated at an early age and meet as adults.

The disorder, which has been recognised only in the past decade, can occur between parents and children and siblings.

Fife police believe the couple have fled Scotland and are staying with relatives in Kettering, Northants.

Detectives are trying to trace the couple.
