Sex attack horror as young Italian couple are surrounded by three migrants who smash into their car,

A man was held down and forced to watch as migrants who smashed into his car raped his 18-year-old fiancée in Italy, according to police in Rome.

The couple had parked in a quiet corner of Tor Tre Teste, a park in the eastern part of the capital, for privacy, minutes before they were surrounded by the group who attacked their vehicle.

Police said the attackers broke the window and first pulled the man, 24, from the car before forcing the woman out as she tried to cover herself with an item of clothing.
