Girl sexually assaulted twice on Newquay to Plymouth train
A 17-year-old girl was sexually assaulted twice - by two different men - on a train as she travelled home from a music festival.
British Transport Police say the "shocking" assaults happened between Newquay and Plymouth on 12 August.
The first man, who was wearing a novelty shark hat, started tickling the girl after she refused a kiss, so she moved seat.
A second man then kissed and touched the girl inappropriately, police say.
