A teenager was raped at Oktoberfest as her boyfriend was held down and forced to watch.

The 18-year-old Brit had gone behind a lorry to have sex with her 24-year-old boyfriend, who is from Ireland, after leaving a drinking tent at about midnight.

The couple, who had just met at Oktoberfest this week, were talking to each other afterwards when two men approached and threatened them.

One of the attackers threw the girl’s partner to the ground and held him down while the other pushed her to the ground and raped her, according to Munich police.

A police spokesman said: “She really fought back and screamed hard but she was nonetheless raped.”

A passer-by heard the screams of the woman and alerted a police patrol – but both the men escaped before officers arrived.
