Raiders armed with knives have robbed a family in their home in Oxford.
The couple and their teenage son were taken into a room by the men who were armed with two knives.
The teenager was assaulted, before the gang searched the house on Farndon Road, and stole a laptop computer and cordless and mobile phones.
They escaped in a small red hatchback car along Warnborough Road.
No one was seriously hurt but police said the family were subjected to a very frightening ordeal.
