The FA have opened an investigation into suspicious betting patterns surrounding the booking of Oxford defender Ciaron Brown in Monday’s FA Cup defeat by Arsenal.

Arsenal ran out 3-0 winners against the League One club thanks to goals from Mohamed Elneny and a brace from Eddie Nketiah. However, the Daily Mail are reporting that the FA have a ‘dossier of evidence regarding supposed corruption.’

This includes alleged phone messages before kick off that claim Brown would be booked in a betting scam. It reportedly cost one bookmaker £1,600 in a single bet with one message showing a bet of around £200 at 8/1. Brown was indeed booked in the 59th minute for a foul on Nketiah, just minutes before Elneny opened the scoring. While the foul itself may not have earned him a yellow card, he then refused to give the ball back to Arsenal to take the free-kick, pushing away Fabio Vieira in the process.

The Daily Mail claim they’ve been told by eyewitnesses that several Arsenal fans were celebrating after Brown was booked, with them saying they’ve won hundreds of pounds.
