These are the first images of the injuries suffered by two of the victims of a machete-wielding gang who terrorised neighbouring homes in a quiet village in Shropshire.
The shocking pictures, which were featured on the BBC's Crimewatch last night, show the injuries caused to a mother and her 15-year-old son in the raids in Wollerton, near Market Drayton, on April 5.
Millions of national television viewers saw a reconstruction of the raids on BBC One as detectives step up their bid to snare the culprits.
The three men, who were also armed with a baseball bat-type weapon, raided the two houses just before 9am.
At one house Kathryn Burton suffered a cut to her fo- rehead and her son William a deep cut to his right hand while trying to protect his mother.
Police said William had surgery on the wound.
At the neighbouring house, Victoria Ratheram, 28, who is eight months pregnant, was tied to a chair while the raiders ransacked the home she shares with husband James, 32.
Detective Chief Inspector Alan Edwards, head of Shropshire CID, said: "This was a violent and terrifying experience for the victims at the two homes.
"I am hoping the Crimewatch reconstruction will persuade people to come forward with information. We are very anxious to identify and trace these men.
"They confronted vulnerable people in their own homes, inflicting nasty injuries to a young boy and his mother as well as assaulting a pregnant woman. They were cowardly crimes."
Both properties were ransacked before the gang fled with a small amount of stolen property in a black Land Rover Discovery taken from one of the homes.
The vehicle was found abandoned within half an hour on the outskirts of the village. Police believe the men then drove off in a silver saloon car.
