FA investigators will look at Oxford United defender Ciaron Brown's phone and scrutinise his calls

FA investigators will look at Oxford United defender Ciaron Brown's phone and scrutinise his recent calls, texts and social media traffic as part of their probe into potential spot-fixing in their FA Cup defeat to Arsenal on Monday. Sportsmail revealed last night that the FA had received evidence of an alleged betting scam. WhatsApp messages from before kick-off claimed that Brown would definitely be booked during the third-round tie on the Monday and the 24-year-old Northern Ireland defender was booked in the 59th minute of the game.

Oxford United are investigating betting on their FA Cup match against Arsenal. Oxford defender Brown was booked twice during the match. The FA will interview all related parties and demand they hand in their phones and laptops. The betting companies are withholding the payment of winning bets until the investigation has concluded. FA have the power to interview the related people. Brown's devices are the primary focus of their initial inquiries. There was a high volume of betting activity on player bookings during this match, which some blame on a pricing error. Other experts suggest it could be due to the rarity of markets on bookies offering betting for League One matches.
