The headline implies something out of a horror movie, like he followed her home, pulled her over under false pretenses, and raped her.
But in reality this is closer to 'fwb crossed his partner's sexual boundaries (after having demonstrated multiple times that he does not respect boundaries)':
Assuming her account is 100% accurate, he ran her plates (creepy as fuck, boundary break #1) to find her on Facebook after they made smiling eye contact with each other, then when he contacted her and admitted that's how he found her, he asked for her phone number and she gave it to him (???). They started texting regularly.
Over the next few months, he came over to her place several times while on duty, and they made out (at least she says they only kissed, but almost definitely more, given the next part) during those visits.
Then one day, he asks to come over and she says she's not up to it, but he comes over anyway (boundary break #2). They make out, he goes down on her, he fingers her, and he has his penis inside her for at least a moment (the way she worded it doesn't sound like there was full on humping happening). She claims the first two were consensual and the last two weren't.
Headline is ridiculously sensationalized. Is it really too boring to describe the actual scenario? Guess that won't get the same number of clicks...
